Sheringham Drive

At about 5:40 a.m. on November 13, 2023, SWAT officers in Mobile, Alabama, banged on the door of a house on Sheringham Drive and shouted "search warrant." Body camera video shows the officers inside less than five seconds later (AL.com, October 2026). The man they wanted, DeAngelo Adjessom, was suspected of distributing marijuana. He was not home (AL.com).

His brother Randall, 16, came around a hallway corner. Less than 10 seconds after the entry, an officer shot him four times. A gun lay beside him. Medical aid began more than four minutes later, and Randall died (AL.com). His family's wrongful death suit was pending when AL.com published the video in October 2026, and no court has ruled on liability (AL.com). Whether Randall knew the men were police, and whether the entry met the knock-and-announce requirement, remain open questions. Chapter 9 lists the known facts.

The Mobile warrant was not a no-knock warrant. The officers knocked, shouted, and came in within seconds, before 6 a.m. Mayor Sandy Stimpson banned most predawn search warrants after the shooting (AL.com). He restricted the hour of entry, not the type of warrant.

Two old rules

English law settled two rules about the front door in 1604. A homeowner who killed a thief breaking into the house committed no felony. A sheriff with a writ could break the door, but only after announcing who he was and why he had come (Liberty Fund, Semayne's Case). American courts adopted both rules. Congress wrote the announcement rule into federal statute in 1917 (State v. Stevens, Abrahamson concurrence). In 1995 a unanimous Supreme Court held that the announcement forms part of what the Fourth Amendment means by a reasonable search (Wilson v. Arkansas).

The two rules fit together only when the resident knows who is at the door. Justice Antonin Scalia named the first interest the announcement protects as "the protection of human life and limb, because an unannounced entry may provoke violence in supposed self-defense by the surprised resident" (Hudson v. Michigan). A no-knock warrant removes the announcement and leaves the homeowner's right of self-defense in place. Several of the deadliest raids in the following chapters began when a resident fired at people he took for burglars.

How the raid grew

Police did not always serve drug warrants with tactical teams. Criminologist Peter Kraska of Eastern Kentucky University estimated about 3,000 SWAT deployments a year in the early 1980s, about 30,000 in 1996, and about 40,000 in 2001 (Balko, Cato Institute, 2006). In 2020 Kraska put the figure at about 60,000 a year (AP via PennLive, 2020). His surveys found that warrant service, mostly for drugs, made up about three-quarters or more of SWAT callouts (Cato).

Federal programs helped pay for the expansion. The Defense Department's 1033 program sent more than $6 billion in military vehicles, weapons, and other gear to local police after 1997 (New York Times, 2017). Drug task force grants and asset forfeiture gave agencies a financial stake in raids (NYT 2017; Cato). Chapter 4 covers the growth in detail.

Nobody counts no-knock warrants nationally. The Council on Criminal Justice stated in 2021 that "there are no national statistics on the number and type of search warrants executed over time" (Council on Criminal Justice). The Center for Justice Research estimated 20,000 to 80,000 no-knock or quick-knock warrants a year (Center for Justice Research, 2024). The estimate spans a factor of four.

The cost

The most complete national count of deaths came from a 2017 New York Times investigation. Reporters found at least 81 civilians and 13 officers killed in forcible-entry search warrant raids from 2010 through 2016 (NYT 2017). The Times called the total a floor.

(NYT 2017)

The counts do not fit a simple claim that no-knock warrants are the deadlier kind. More civilians died in knock-and-announce raids. More officers died in no-knock raids, and officers made up about 20 percent of the dead in no-knock raids against about 10 percent in knock-and-announce raids (CCJ). Without a count of raids of each type, nobody can compute a death rate for either. Chapter 6 works through rough estimates and their limits.

The deaths are only part of the cost. Officers have raided the wrong house, burned a toddler with a flashbang grenade, and killed people who were not the target of the warrant (Chapters 9 to 11). Officers who lied to obtain warrants have gone to prison, and cities have paid settlements (Chapter 13).

Growing or shrinking

No-knock policy has moved in opposite directions since 2020.

State counts are falling where legislatures acted. Federal policy moved the other way in 2026. Former prosecutors told MS NOW that the risk of evidence destruction could be argued in nearly every search (MS NOW). The 1970 federal no-knock statute rested on the same ground. Congress repealed that statute in 1974, after federal agents raided two innocent households in Collinsville, Illinois (Chapter 2). No national data exist to show whether the total number of sudden forced entries is rising or falling.

Police still serve warrants on houses where children sleep, where residents keep guns for protection, and where the informant who supplied the address may have lied (Chapters 7 to 9). In January 2025, Knox County, Tennessee, deputies served a search warrant at the home of Daevon Saint-Germain, 18, and shot him. Deputies said he pulled out a rifle. His family's pending lawsuit alleges a flashbang entry and disputes the deputies' account. Tennessee had banned no-knock warrants in 2021 (Atlanta Black Star, 2026; Tennessee General Assembly). Chapter 12 lists the known facts and the open questions in that case.

The question

A common belief holds that no-knock warrants end in violence more often than other warrants. The record supports part of that belief, contradicts part, and leaves part unmeasured.

Semayne's Case, 1604

In 1604 the Court of King's Bench decided a dispute over a debt. Richard Gresham had died owing money to Peter Semayne. Gresham's goods sat in a house owned by George Berisford. The sheriff of London tried to collect, and Berisford kept the door shut. The judges used the case to state two rules that still govern American police.

Sir Edward Coke reported the first rule in words most Americans can recite without knowing the source: "That the house of every one is to him as his Castle and Fortress as well for defence against injury and violence, as for his repose" (Liberty Fund, Semayne's Case). The same passage says that if "theeves come to a mans house to rob him, or murder, and the owner or his servants kill any of the theeves in defence of himself and his house, it is no felony" (Liberty Fund).

The second rule limited the first. The castle protected the owner against private intruders. It did not protect the owner against the King's lawful process. A sheriff carrying a writ could break a door, but only after he announced himself, stated his purpose, and asked to be let in. American courts later called that requirement the knock-and-announce rule.

Both rules sit in the same 400-year-old case. The homeowner may kill a thief. The sheriff must say who he is. A no-knock entry weakens the second rule and leaves the first one in force.

What the announcement was for

The Supreme Court has listed the interests the announcement protects. Justice Antonin Scalia, writing for the majority in Hudson v. Michigan (2006), named three (Hudson v. Michigan, 547 U.S. 586):

1. "One of those interests is the protection of human life and limb, because an unannounced entry may provoke violence in supposed self-defense by the surprised resident."
2. Protection of property. The announcement gives residents "the opportunity to comply with the law and to avoid the destruction of property occasioned by a forcible entry."
3. Privacy and dignity. The rule "assures the opportunity to collect oneself before answering the door."

Scalia wrote the first interest in the same opinion that removed the most practical penalty for ignoring the rule. Chapter 3 covers that opinion.

The rule crosses the Atlantic

The framers of the Fourth Amendment did not write "knock" into the text. The Amendment protects "the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." In 1995 a unanimous Supreme Court held that the old announcement rule forms part of what "unreasonable" means (Wilson v. Arkansas, 514 U.S. 927). Justice Clarence Thomas wrote that the Court had "little doubt that the Amendment's Framers thought that whether officers announced their presence and authority before entering a dwelling was among the factors to be considered in assessing a search's reasonableness" (Wilson).

Congress put the rule into federal statute in 1917 (State v. Stevens, Abrahamson concurrence). The current version, 18 U.S.C. § 3109, reads: "The officer may break open any outer or inner door or window of a house, or any part of a house, or anything therein, to execute a search warrant, if, after notice of his authority and purpose, he is refused admittance or when necessary to liberate himself or a person aiding him in execution of the warrant" (Stevens concurrence quoting 18 U.S.C. § 3109).

Miller v. United States, 1958

The modern line of cases begins with a heroin sale in Washington, D.C. At 3:45 a.m. on March 25, 1955, federal narcotics agent Wilson and Metropolitan Police officer Wurms went to the apartment of William Miller. Wurms knocked. Someone inside asked, "Who's there?" Wurms answered, in a low voice, "Police." Miller opened the door on its chain, asked what the officers wanted, and tried to close it. In Wurms's words, "we put our hands inside the door and pulled and ripped the chain off, and entered" (Miller v. United States, 357 U.S. 301).

The officers had no warrant. The Supreme Court reversed Miller's conviction. Justice William Brennan wrote that Miller "could not be lawfully arrested in his home by officers breaking in without first giving him notice of their authority and purpose" (Miller). He added two sentences that later courts quoted often:

"The burden of making an express announcement is certainly slight. A few more words by the officers would have satisfied the requirement in this case."

"The requirement of prior notice of authority and purpose before forcing entry into a home is deeply rooted in our heritage, and should not be given grudging application." (Miller)

The two exceptions

The common law never treated the announcement as absolute. Thomas wrote in Wilson that "the common law principle was never stated as an inflexible rule requiring announcement under all circumstances" (Wilson). He named three examples of countervailing interests: "the threat of physical harm to police, the fact that an officer is pursuing a recently escaped arrestee, and the existence of reason to believe that evidence would likely be destroyed if advance notice were given" (Wilson).

Those exceptions now take two forms (Congressional Research Service, LSB10499):

The Congressional Research Service describes the difference as timing. With a no-knock warrant, officers anticipate the danger and obtain "pre-search judicial approval to enter without knocking" (CRS). Without one, the danger may arise "as late as when officers are at the door" (CRS). Some courts have held that a no-knock warrant relieves officers of the duty to reassess the danger at the scene. The CRS notes that a warrant could then permit unannounced entry "even if the circumstances that supported it no longer exist" (CRS).

Coke's report of Semayne's Case ends its castle passage with a Latin maxim: domus sua cuique est tutissimum refugium, "everyone's house is his safest refuge" (Liberty Fund).

Two statutes in one year

Congress passed two no-knock laws in 1970. The District of Columbia Court Reform and Criminal Procedure Act covered police in the capital. Section 509 of the Comprehensive Drug Abuse Prevention and Control Act, Public Law 91-513, added a no-knock provision for federal drug agents at 21 U.S.C. § 879(b) (U.S. Code, 21 U.S.C. § 879, notes). Several states passed similar laws.

The New York Times summarized the standard in 1973. Police could obtain a special warrant and enter without notice when they had probable cause to believe that evidence could be quickly destroyed or that an announcement could endanger officers (Andrew H. Malcolm, New York Times, June 25, 1973).

Law reviews criticized the statutes as they passed. The Minnesota Law Review, the Yale Law Journal, and the Washington University Law Quarterly all published notes on the new authority between 1970 and 1971 (State v. Stevens, Abrahamson concurrence).

The Office of Drug Abuse Law Enforcement

President Richard Nixon created the Office of Drug Abuse Law Enforcement, called ODALE, in January 1972 (NYT 1973). The office targeted street-level dealers. Its motto was "Caveat Vendor," Latin for "let the seller beware" (NYT 1973). ODALE officials told the Times they had conducted "about 100" no-knock raids. The Bureau of Narcotics and Dangerous Drugs, which pursued larger traffickers, said it had conducted "two or three" (NYT 1973).

Collinsville, Illinois, April 1973

On the night of April 23, 1973, more than 15 men in street clothes forced their way into the Collinsville apartment of Herbert Giglotto. Giglotto and his wife were asleep. The men handcuffed the couple, held them at gunpoint, ransacked the apartment, and shouted obscenities. About half an hour later, agents raided the home of Donald Askew across town (NYT 1973).

Both addresses were wrong. The agents carried no search warrants and no arrest warrants. They did not identify themselves until well into each raid. They worked for ODALE. The agency suspended the agents with pay while a grand jury investigated (NYT 1973).

The Collinsville raids drew national attention. Justice Shirley Abrahamson of the Wisconsin Supreme Court later wrote that after "two no-knock drug raids on innocent households in Collinsville, Illinois, the Drug Enforcement Administration issued guidelines requiring high approval before federal agents could request a no-knock warrant" (Abrahamson concurrence).

The Times investigation

Andrew Malcolm spent eight weeks on the story that ran on June 25, 1973. He found at least four deaths in the preceding three years. He found that mistaken and aggressive raids were not isolated (NYT 1973). The article did not claim that every raid involved a no-knock warrant. Some raids had warrants and some did not. In some, agents never identified themselves at all.

Three of Malcolm's cases bear directly on the question of armed residents.

(NYT 1973)

Mr. Herman told the Times: "If I had a gun, I would have fired, thinking they were burglars" (NYT 1973). One agent with about 200 raids behind him said: "You wonder what you would do if your door crashed down at 3 AM and you had a gun. You would likely fire, right?" (NYT 1973).

Agents described the announcement as a formality. One said: "You might quietly say, 'Open up! Police!' just before you break down the door" (NYT 1973). Another called no-knock raids "the most terrifying" and said "the risks might outweigh the benefits" (NYT 1973).

The article also tied the raids to growth. The Bureau of Narcotics and Dangerous Drugs had 615 agents and a $14 million budget in 1968. By 1973 it had 1,586 domestic agents and a $74 million budget. Its training academy offered a 10-week course with 26 hours on the Fourth Amendment. Attendance was optional, and some agents involved in mistaken raids had not taken the course (NYT 1973).

Repeal

The Senate voted 64 to 31 on July 11, 1974, to repeal the federal no-knock provisions (New York Times, July 12, 1974). Senator Sam Ervin of North Carolina said it "sanctioned the methods of a common burglar" (NYT 1974). The Congressional Record for that debate records another senator calling the 1970 statute "an invitation to official lawlessness" (120 Cong. Rec. 22,898 (1974), quoted in the Abrahamson concurrence).

President Gerald Ford signed the repeal on October 26, 1974, as part of Public Law 93-481 (U.S. Code notes). The law repealed both § 879(b) and the District of Columbia provision (U.S. Code notes).

Congress never passed another general no-knock statute. Judges filled the gap. Twenty years after repeal, Abrahamson summarized the federal experiment in one line: "a federal attempt to respond to increasing drug-related crime and violence in the early 1970s by relaxing search regulations miscarried" (Abrahamson concurrence).

The officer-safety record in 1994

Abrahamson's 1994 concurrence also tested the claim that drug warrants had grown more dangerous for officers. Her majority colleagues had written that "the violence associated with drug trafficking today places law enforcement officers in extreme danger" (Stevens). She checked the FBI numbers.

(1992 Sourcebook of Criminal Justice Statistics, reproduced in the Abrahamson concurrence. The concurrence prints the 1978 to 1981 drug figure as "53 / 5.8%"; the count and percentage do not reconcile, and the table reproduces the concurrence as printed.)

In 1991, three officers died in drug-related matters nationwide, nine in domestic violence situations, and six while handling prisoners (Stevens). Abrahamson acknowledged that the drug-related percentage had risen somewhat. She noted that the records did not show how many deaths occurred during warrant service (Stevens). The same gap in the data remains in 2026.

Ker v. California, 1963

Los Angeles County officers used a passkey from the building manager to enter the apartment of George and Diane Ker without announcing themselves. They found marijuana. The Supreme Court upheld the search 5 to 4 (Ker v. California, 374 U.S. 23). The plurality accepted the officers' belief that the Kers might destroy the drugs. Justice William Brennan wrote the dissent for four justices. He argued that the Constitution forbids unannounced entry except in narrow emergencies, and he quoted the castle principle from Semayne's Case (Ker).

Ker applied the Fourth Amendment to state police. The justices split on whether that Amendment required an announcement at all. Thirty-two years passed before the Court answered.

Wilson v. Arkansas, 1995

In 1995 the Court decided that the Fourth Amendment does include the announcement rule. Justice Clarence Thomas wrote for a unanimous Court: "The common-law 'knock and announce' principle forms a part of the reasonableness inquiry under the Fourth Amendment" (Wilson v. Arkansas, 514 U.S. 927). The same opinion left room for exceptions and sent the case back to the Arkansas courts to decide whether one applied.

Richards v. Wisconsin, 1997

Wisconsin had adopted a blanket rule. Its supreme court held that police never needed to knock when serving a felony drug warrant. Justice Abrahamson's concurrence in that 1994 case appears in Chapter 2.

On December 31, 1991, Madison officers went to the motel room of Steiney Richards with a drug warrant. One officer posed as a maintenance worker. Richards opened the door, saw a uniformed officer behind him, and slammed it shut. "After waiting two or three seconds, the officers began kicking and ramming the door to gain entry to the locked room" (Richards v. Wisconsin, 520 U.S. 385).

The Supreme Court rejected Wisconsin's blanket rule. "The Fourth Amendment does not permit a blanket exception to the knock-and-announce requirement for felony drug investigations" (Richards). The Court reasoned that categories would swallow the rule: "If a per se exception were allowed for each category of criminal investigation that included a considerable, albeit hypothetical, risk of danger to officers or destruction of evidence, the knock-and-announce element of the Fourth Amendment's reasonableness requirement would be meaningless" (Richards).

The Court then set the standard that still governs. "A 'no-knock' entry is justified when the police have a reasonable suspicion that knocking and announcing their presence, under the particular circumstances, would be dangerous or futile, or that it would inhibit the effective investigation of the crime" (Richards). The next sentence matters as much: "This showing is not high" (Richards).

Richards also blessed no-knock warrants. "The practice of allowing magistrates to issue no-knock warrants seems entirely reasonable when sufficient cause to do so can be demonstrated ahead of time" (Richards). The Court affirmed Richards's conviction because his slammed door gave officers reason to fear destruction of evidence.

Reasonable suspicion

Reasonable suspicion is the lowest standard in Fourth Amendment law. It requires specific facts, not a hunch, but it requires less than probable cause. Probable cause is the standard for the warrant itself. Richards therefore lets a judge authorize a no-knock entry on a weaker showing than the judge needs to authorize the search.

United States v. Banks, 2003

Federal and local officers went to the North Las Vegas apartment of LaShawn Banks at 2 p.m. on a weekday with a warrant to search for cocaine. They knocked loudly and announced "police search warrant." They waited 15 to 20 seconds. Then they broke the door with a battering ram (United States v. Banks, 540 U.S. 31).

Banks was in the shower. He testified that he heard nothing until the door crashed open, and he came out "dripping to confront the police" (Banks). A unanimous Court held the entry lawful. Justice David Souter wrote that "what matters is the opportunity to get rid of cocaine, which a prudent dealer will keep near a commode or kitchen sink" (Banks). The Court measured the wait against the time needed to flush drugs, not the time needed to reach the door: "it is imminent disposal, not travel time to the entrance, that governs when the police may reasonably enter" (Banks).

Banks's actual location did not change the answer. "The facts known to the police are what count in judging reasonable waiting time" (Banks).

The Council on Criminal Justice later concluded that Banks "blurs the legal line" between a no-knock entry and a knock-and-announce entry (Council on Criminal Justice, 2021). A resident asleep at the back of a house may not reach the door in 15 seconds. To that resident, a 15-second entry and a no-knock entry look the same. Lower courts have generally found waits under five seconds too short and waits over 10 seconds usually long enough, with wide variation (Radley Balko, Cato Institute, 2006).

Hudson v. Michigan, 2006

Detroit officers went to the home of Booker Hudson with a warrant for drugs and guns. They announced themselves and waited only three to five seconds before entering. Michigan conceded the entry violated the knock-and-announce rule. The trial court admitted the drugs and the gun anyway (Hudson v. Michigan, 547 U.S. 586).

The Supreme Court ruled 5 to 4 that a knock-and-announce violation does not require exclusion of the evidence. Justice Scalia wrote that the rule had "never protected" a resident's "interest in preventing the government from seeing or taking evidence described in a warrant" (Hudson). He listed the costs of suppression, including "a constant flood of alleged failures to observe the rule" (Hudson). He predicted that heavy penalties would make officers wait too long, "producing preventable violence against officers in some cases, and the destruction of evidence in many others" (Hudson).

Scalia pointed to other deterrents. He cited civil rights suits, attorney fee awards under 42 U.S.C. § 1988, and "the increasing professionalism of police forces, including a new emphasis on internal police discipline" (Hudson). He wrote: "As far as we know, civil liability is an effective deterrent here" (Hudson).

The Breyer dissent

Justice Stephen Breyer wrote for four dissenters. He said the decision "destroys the strongest legal incentive to comply with the Constitution's knock-and-announce requirement" (Hudson, Breyer dissent). He challenged the civil-suit argument directly:

"The majority, like Michigan and the United States, has failed to cite a single reported case in which a plaintiff has collected more than nominal damages solely as a result of a knock-and-announce violation." (Breyer dissent)

Breyer called the majority's view of civil liability "a support-free assumption" (Breyer dissent). He predicted that "officers will almost always know ex ante that they can ignore the knock-and-announce requirement without risking the suppression of evidence" (Breyer dissent). Ex ante means "beforehand."

The legal map after Hudson

The four decisions produced a simple structure.

The Congressional Research Service summarized the remedies in June 2020. Officers who violate the rule may face civil lawsuits and "internal police discipline." Under Hudson, the evidence stays in (CRS, LSB10499). Chapter 13 tests the civil-suit remedy that Scalia relied on.

Booker Hudson's conviction for drug possession stood.

From barricades to warrants

SWAT stands for Special Weapons and Tactics. Los Angeles and other cities formed the first teams in the late 1960s and early 1970s (New York Times, 2017). The teams trained for hostage takings, barricaded gunmen, and riots. Those events were rare. Warrant service was not.

Criminologist Peter Kraska of Eastern Kentucky University tracked the change through national surveys. His estimates, reported by Radley Balko in a 2006 Cato Institute paper, show the scale (Balko, Cato Institute, 2006):

The New York Times reported Kraska's later estimate that deployments rose about 15-fold from 1980 to 2000 (NYT 2017). In 2020 Kraska estimated about 60,000 a year, according to the Associated Press (AP via PennLive, 2020). Nobody keeps an official national count. The Council on Criminal Justice stated in January 2021 that "there are no national statistics on the number and type of search warrants executed over time" (Council on Criminal Justice). The Center for Justice Research estimated 20,000 to 80,000 no-knock or quick-knock warrants a year (Center for Justice Research, 2024). The width of that range reflects the gap in the data.

What the teams did

Kraska's surveys found that warrant service made up about 80 percent of SWAT callouts in small and medium cities and about 75 percent in large cities (Cato 2006). Local numbers followed the same pattern.

The American Civil Liberties Union study found that no-knock warrants were used or probably used in about 60 percent of the drug-search deployments it examined (ACLU 2014). The ACLU coded incomplete reports as "likely" or "unknown" and did not claim national rates (ACLU).

Equipment

The Defense Department's excess property program, known as the 1033 program, sent more than $6 billion in military vehicles, weapons, and other equipment to local police after 1997 (NYT 2017). The Bureau of Justice Statistics found that nearly every agency with at least 100 officers had a full-time tactical unit or took part in a shared one. About a third of smaller agencies did the same (NYT 2017).

Money

Federal grants paid for drug task forces. Asset forfeiture let agencies keep a share of seized cash and property. In Utah, search warrant executions accounted for 29 percent of all forfeitures in 2015, according to a state report cited by the Times (NYT 2017). The National Law Journal estimated that payments to informants rose from $25 million in 1985 to about $97 million in 1993 (Cato 2006).

What the raids found

Several studies counted results. The counts vary by place and method, and none covers the nation.

(Sources: Cato 2006; ACLU 2014; Jonathan Mummolo, PNAS, 2018.)

The Times found raids served on small stakes. In Marine City, Michigan, in 2011, officers used dynamic entry to serve a warrant for "any and all evidence pertaining to graffiti including but not limited to, spray paint containers, markers, notebooks, and photographs." Residents said officers forced them to the floor at gunpoint and found nothing (NYT 2017).

Who was inside

The ACLU found that 42 percent of people affected by SWAT warrant deployments were Black and 12 percent were Latino, among cases where race was recorded (ACLU 2014). More than a third of reports did not record race (ACLU). Children were documented as present in 14 percent of deployments; another 35 percent did not say (ACLU). A Minneapolis review of no-knock warrants served from September 2021 through January 2022 found that 74 percent were served on Black individuals. Black residents made up 18 percent of the city's population in the 2020 census (Maryland HB 464 fiscal note, 2026).

Disparity in who is raided does not by itself show why. Drug enforcement priorities, neighborhood deployment, informant networks, and the location of open-air markets all affect the numbers. The data sets above do not separate those factors.

The trainers' warning

The National Tactical Officers Association, the main professional body for SWAT officers, urged sparing use of dynamic entry. Robert Chabali, a former chairman, recommended never using it for narcotics warrants: "You definitely don't go in and risk your life for drugs" (NYT 2017). Phil Hansen, another former chairman, called dynamic entry "a one-size-fits-all solution to tactical problems" (NYT 2017). Bob Bushman, president of a national narcotics officers' coalition, defended the practice. He called no-knock warrants "a tool that should stay in the toolbox" (NYT 2017).

In 2006 Balko counted at least 780 flawed paramilitary raid cases that reached appellate courts between 1989 and 2001, drawing on Kraska's work (Cato 2006). Appellate cases represent only the raids that produced a criminal appeal.

Why definitions matter

The question behind this book sounds simple. Do no-knock warrants end in violence more often than other warrants? Answering it requires a definition of "no-knock." The courts, the statutes, and the officers at the door use the word differently. The New York Times concluded in 2017 that "in practice, there is often little difference" between a no-knock warrant and a knock-and-announce warrant (NYT 2017).

The vocabulary

The label and the door

Four facts show how far the label can drift from the event.

First, the federal Justice Department found in 2023 that Louisville officers "executed no-knock warrants far more often than they applied for them" (Louisville Public Media, March 8, 2023). A warrant labeled knock-and-announce became a no-knock entry at the door.

Second, the Supreme Court approved a 15 to 20 second wait in Banks (2003). Balko reported that officers in some departments waited 10 or 15 seconds even when residents were likely asleep. Muncie, Indiana, officers testified that they typically waited five seconds (Cato 2006).

Third, the person inside often cannot tell which kind of warrant police hold. In the Myrtle Beach shooting of Julian Betton on April 16, 2015, the warrant did not authorize unannounced entry. Officers said they knocked and announced. Porch video, without audio, showed no pause before the ram hit the door. A neighbor told investigators he was "100 percent sure" no warning was given (NYT 2017).

Fourth, warrants rarely specify tactics. The ACLU found no general rule forbidding any particular method of entry (ACLU 2014). A judge who refuses a no-knock request does not control whether the team uses a ram, a flashbang, or a 5 a.m. arrival.

Maine's answer

Maine wrote the problem into statute in 2021. Its law defines a no-knock warrant to include any warrant "executed without waiting at least 20 seconds after the announcement of authority and purpose before making entry" (Maine Revised Statutes, Title 15, § 57). Under that definition, the 15-second entry the Supreme Court approved in Banks counts as a no-knock entry in Maine.

Maine permits a no-knock warrant only when the warrant "clearly states" that notice would create "an imminent risk of death or bodily harm" to an officer, a person inside, or a person nearby. The judge must verify that risk from the affidavit. The entry team must wear uniforms, and only officers trained on "stun grenade, stun, distraction or other similar devices" may use them (Maine § 57). The statute does not require body-camera recording.

Minneapolis adopted a similar rule by policy: a 20-second wait after the announcement by day and 30 seconds at night (MPR News, August 12, 2025).

How the label affects the numbers

Every count in Chapter 6 depends on how its authors sorted raids. The Times sorted by the type of warrant the judge signed. The Council on Criminal Justice warned that the Banks standard "blurs the legal line" (CCJ). A study that sorts by the paper will miss quick-knock entries that look like no-knock entries from inside the house. A study that sorts by what the residents heard will depend on disputed testimony.

Neither method is wrong. Each answers a different question. The paper answers what the judge approved. The door answers what the resident experienced. The violence in this book happens at the door.

The Maine statute that put a number on the difference is Public Law 2021, chapter 267 (Maine § 57).

The count nobody keeps

No federal agency counts search warrants, no-knock warrants, or deaths during warrant service. The New York Times reported in 2017 that there was "no federal mandate" for agencies to report SWAT operations and that only two states had ever required it (NYT 2017). The Council on Criminal Justice repeated the point in 2021: "no national statistics" exist on the number and type of warrants served (CCJ).

A rate needs two numbers: the events and the opportunities. For no-knock raids, researchers have partial counts of deaths and almost no reliable count of raids. That limit applies to every figure below.

The New York Times count, 2010 to 2016

The most complete national count comes from a 2017 Times investigation. Reporters used dozens of open-records requests and thousands of pages of police and court files. They found at least 81 civilians and 13 law enforcement officers killed in forcible-entry search warrant raids from 2010 through 2016 (NYT 2017). The Times described the totals as a floor, not a complete census.

(Counts from NYT 2017. Officer shares calculated from those counts and match the shares reported by the Council on Criminal Justice.)

Two findings stand out.

1. More civilians died in knock-and-announce raids than in no-knock raids: 47 against 31.
2. More officers died in no-knock raids than in knock-and-announce raids: 8 against 5. Officers made up about one in five deaths in no-knock raids and about one in 10 in knock-and-announce raids.

The raw civilian count does not show that knock-and-announce raids are more dangerous. Police serve far more knock-and-announce warrants than no-knock warrants, so a larger death count could reflect volume alone. The count also does not show that no-knock raids are safer for civilians. Without the number of raids of each type, neither conclusion follows.

Estimating the denominator

Utah is the only state that has published a multiyear split between the two warrant types. In 2014 and 2015, about 40 percent of Utah warrants served by tactical teams were no-knock (NYT 2017). In 2019, about a quarter of nearly 400 warrants were no-knock (AP via PennLive, 2020). Columbus, Ohio, served 93 of 331 warrants without a knock in 2019, or 28 percent (AP via PennLive).

Those three figures suggest that no-knock warrants made up roughly a quarter to two-fifths of tactical warrant service in places that counted. If the national share fell in the same range during 2010 to 2016, the Times deaths compare as follows.

This comparison rests on stacked assumptions. Utah, Columbus, and a 2010 to 2016 national sample may differ. The Times count is incomplete, and 13 officer deaths form a small sample. Within those limits, the comparison points in one direction: no-knock raids appear to account for more than their share of deaths, and the excess is largest for officers.

The selection problem

A higher death rate in no-knock raids does not prove the lack of announcement caused the deaths. Judges grant no-knock warrants when police swear that the person inside is armed or dangerous. If those affidavits are accurate, no-knock raids target more dangerous people, and more violence would follow under any entry method.

Three facts weigh against selection as the whole explanation.

• Affidavits often overstate danger. In Denver in 1999, police affidavits claimed weapons would be present in about 8 of 10 raids, and only 7 of 163 affidavits alleged anyone had seen the suspect with a gun (Cato 2006). The ACLU found weapons in 35 percent of drug searches where officers expected them (ACLU 2014).
• Several officer deaths involved residents with no violent record who fired at what they believed were burglars. Henry Magee in Texas had only misdemeanor marijuana and drunk-driving convictions (NYT, Texas raids). Chapter 8 covers these cases.
• The Times found that in some raids where an officer died, suspects with no history of violence and small quantities of drugs faced capital murder charges (Texas Monthly, 2019).

Selection and surprise probably both contribute. The available data cannot separate them.

State reporting

Maryland required every SWAT team to report every deployment from fiscal 2010 through 2014. The law expired on June 30, 2014 (Maryland HB 464 fiscal note). Political scientist Jonathan Mummolo of Princeton analyzed the full Maryland record of about 8,200 deployments (Mummolo, PNAS, 2018).

(Mummolo 2018)

Mummolo described violence as rare. Shots were fired in about 100 deployments. The data did not record whether a warrant was no-knock (Mummolo). His national analysis of roughly 9,000 agencies found "no evidence that acquiring a SWAT team lowered crime or promoted officer safety" (Mummolo).

Maryland restored reporting in 2021. The Governor's Office of Crime Prevention and Policy reported 1,296 SWAT deployments by 34 agencies in 2025, with forcible entry in 48 percent. Five people were injured and three were killed. Firearms were discharged in two deployments. The state recorded 29 no-knock warrants that year (Maryland GOCPP, 2026). The report does not say whether any death or injury occurred during a no-knock entry (GOCPP).

Maryland's no-knock count fell from 59 in 2023 to 41 in 2024 and 29 in 2025 (HB 464 fiscal note; GOCPP). Maryland law requires approval by a supervisor and the State's Attorney and limits no-knock service to 8 a.m. to 7 p.m. absent exigent circumstances (HB 464 fiscal note).

One department's own review

After the Harding Street raid in January 2019, Houston Police Chief Art Acevedo reviewed every narcotics search warrant his department executed from January 1, 2014, through December 31, 2018. He counted 1,736 warrants and one officer-involved shooting (Texas Monthly, 2019). The records did not show how many were no-knock (Texas Monthly).

Houston's figure shows that most warrant service ends without gunfire. Scaled up, the same rate still matters. One shooting per 1,736 warrants, applied to Kraska's 2001 estimate of 40,000 deployments a year, would produce about 23 police shootings a year (Cato 2006). The calculation assumes Houston's rate holds nationally, which nobody has tested.

What officers said

Researchers led by Brandon del Pozo interviewed narcotics officers in a large Midwestern department in January and February 2022. The department had shifted away from no-knock drug warrants in early 2020. Five of six officers said the change improved safety for officers and civilians (del Pozo et al., preprint). One said: "most of the shootings we've gotten into was on no-knock search warrants" (del Pozo).

The sixth officer disagreed. He said no-knock entry let officers take control before someone could "think or grab a gun." He also said: "I haven't looked at the [shooting] numbers" (del Pozo). The study reported no numbers on either side. Its authors wrote that comparative studies of warrant methods had not, to their knowledge, been conducted (del Pozo).

What the evidence supports

The Times summed up the overlap in one phrase: in practice, "there is often little difference" between the two warrant types (NYT 2017). The violence follows the forced, sudden entry. The no-knock warrant is the most direct legal route to that entry, but not the only one.

The Times count ended on December 31, 2016. No national count has replaced it.

The affidavit

Every warrant starts with an affidavit, a sworn statement by an officer. The officer describes what he knows and how he knows it. A judge reads the affidavit and decides whether it shows probable cause to search. If the officer asks for a no-knock warrant, the judge also decides whether the affidavit shows reasonable suspicion of danger or destruction of evidence.

The judge sees only the paper. The judge does not hear from the person who lives at the address. The judge often cannot test the informant's account. Several of the deadliest raids in this book began with paper that was wrong.

Burleson County, Texas, December 2013

On December 13, 2013, a jailed man named Joshua Aaron Hall told sheriff's investigator Gene Hermes that Henry Magee grew marijuana in his trailer on Deer Running Road in Somerville. Hall said he had seen about 12 six-foot stalks. He said Magee had two rifles and three handguns and was "ready for war" (NYT, Texas raids, 2017).

Hall was in jail for a probation violation and wanted rehabilitation instead of prison. Investigators knew he was untested as an informant. Court documents did not show that they checked his record, corroborated his story, or arranged a controlled buy. Their legwork consisted mostly of driving past the trailer and taking photographs (NYT, Texas).

Five days later, Investigator Adam Sowders applied for a no-knock warrant. His affidavit left out that Hall had described Magee as "laid-back," that Hall wanted leniency, and that Magee had no violent record. It included this line: "Hall advised that Magee has made the statement that he is not afraid to use the weapons that he has" (NYT, Texas). District Judge Reva Towslee Corbett signed the warrant that afternoon (NYT, Texas).

The raid recovered 10 cannabis plants and jars and baggies of marijuana weighing 4.39 ounces. No six-foot plants were found (NYT, Texas). Adam Sowders died in the raid. Chapter 8 covers the shooting.

Killeen, Texas, May 2014

Killeen narcotics investigator John Moseley requested a no-knock warrant for the apartment of Marvin Guy on May 8, 2014. An informant had said Guy sold cocaine from his car and carried a handgun. Officers had watched the apartment intermittently and sent the informant back, but arranged no buy. Municipal Judge Mark Kimball read and signed the affidavit in five minutes (NYT, Texas).

Police later described the drugs found as "approximately one gram of suspected cocaine" (NYT, Texas).

Cornelia, Georgia, May 2014

Habersham County deputy Nikki Autry obtained the no-knock warrant for the house where 19-month-old Bou Bou Phonesavanh was sleeping. Her affidavit stated that a "true and reliable" confidential informant had bought methamphetamine at the house and that she had confirmed "heavy traffic" there (NYT 2017).

The Times found that the informant named in the affidavit, James Alton Fry Jr., had not made the buy. The buyer was Larry Wood. Fry had never made a prior buy. Autry had not watched the house (NYT 2017). Magistrate Judge James Butterworth testified that he would not have approved the warrant without the inaccurate details (Jacob Sullum, Reason, 2025). Acting U.S. Attorney John Horn said: "Without her false statements, there was no probable cause to search the premises for drugs or to make the arrest" (Reason 2025).

A federal jury acquitted Autry in December 2015. Her defense argued that a supervisor had prepared the affidavit and that she was a scapegoat (Reason 2025).

Houston, January 2019

Houston narcotics officer Gerald Goines swore that a confidential informant had bought heroin from a man at 7815 Harding Street and had seen a 9mm pistol there. The affidavit described the informant as "credible and reliable on many prior occasions" (Texas Monthly, 2019). A municipal judge signed a no-knock warrant at 1:30 p.m. on Monday, January 28, 2019. Police arrived within three and a half hours (Texas Monthly).

Goines had invented the buy. Prosecutors later showed he was 20 miles away on the evening he claimed to have bought heroin himself (Reason, September 25, 2024). A neighbor, Patricia Garcia, had made false 911 calls describing the couple as armed heroin dealers. She had no daughter, though her calls claimed her daughter had used heroin in the house (Reason 2024; Houston Public Media, 2021).

The raid killed Dennis Tuttle and Rhogena Nicholas. Officers found personal-use amounts of marijuana and cocaine, no heroin, and no 9mm pistol (Reason 2025). Goines had obtained nearly 100 no-knock warrants over 12 years. He almost always claimed informants had seen firearms. He reported finding guns once (Reason 2025).

Louisville, March 2020

Detective Joshua Jaynes obtained the warrant for Breonna Taylor's apartment. He wrote that he had verified with a U.S. postal inspector that Jamarcus Glover received packages there. He later admitted the claim was untrue (Reason 2025). Federal prosecutors alleged in 2022 that the affidavit "contained false and misleading statements, omitted material facts, relied on stale information, and was not supported by probable cause" (Reason 2025). Detective Kelly Goodlett pleaded guilty to conspiring with Jaynes to falsify the warrant (Reason 2025). The charges against Jaynes and Sgt. Kyle Meany remain pending. Chapter 12 covers what is known.

Atlanta, November 2006

Atlanta narcotics officers obtained a no-knock warrant for the Neal Street home of Kathryn Johnston on the claim that an informant had bought drugs there (Atlanta Journal-Constitution). Johnston was 92. When officers broke in, she fired one shot. Officers fired 39 shots and killed her (Wikipedia, Shooting of Kathryn Johnston). No drugs were found. Officers planted marijuana from a different raid (AJC). Chapter 13 covers the prosecutions.

The pattern in numbers

The individual cases fit wider findings.

(Sources: Cato 2006; Mississippi Today, March 20, 2025.)

The Mississippi review found boilerplate in place of facts. In January 2020, Monroe County Justice Court Judge Brandon Davis signed a warrant requesting a no-knock search "due to officer safety and the protection of further evidence," with no detailed reasons in either the warrant or the affidavit (Mississippi Today). Former federal magistrate Stephen Smith reviewed the Monroe County warrants. "Every one of these granted no-knock authority," he said, but "only one attempted to justify it" (Mississippi Today). Henry Schultz, who helped argue Richards v. Wisconsin, said: "We're back to where we were" (Mississippi Today).

Some judges changed practice. Monroe County Judge Sarah Cline Stevens added handwritten details to a February 2020 application before approving it: the target "came to the door with a gun (sawed off shotgun and pistol)" during an earlier warrant (Mississippi Today). Experts judged that entry adequate. By early 2025 the county sheriff had removed the boilerplate from applications (Mississippi Today).

Worcester, August 2015

Massachusetts offered a smaller example. In August 2015, Worcester assistant clerk-magistrate Brenda Seaver approved a no-knock warrant based on one informant, with no surveillance, despite records showing the suspect had moved. The 5 a.m. raid detained the new tenants and two children. Officers found no contraband. The tenants sued (NYT 2017).

The informant in the Magee case asked investigators, if Magee grabbed a gun, to "try not to shoot him" (NYT, Texas).

Two rules collide

Semayne's Case gave the homeowner the right to kill a thief who breaks in at night. Modern law kept that right. Most states recognize some form of the castle doctrine, the principle that a person may use deadly force against an intruder in the home. The Associated Press reported in 2020 that 27 states also had stand-your-ground laws (AP via PennLive, 2020).

Kay Levine, a law professor at Emory University, described the problem in 2020: "Given the collision course that we are on, with the extent that people have firearms in their house and the castle doctrine," allowing no-knock warrants is "deeply problematic" (AP via PennLive). Justice Abrahamson made a similar point in 1994. She cited a federal estimate of about 200 million firearms nationwide, "about one per person," and a survey finding that 55 percent of Wisconsin residents had guns (Abrahamson concurrence).

In each case below, the central factual issue was whether the resident knew the people breaking the door were police. The evidence on that issue came largely from disputed testimony about an announcement made seconds before or during the entry.

Henry Magee, Somerville, Texas

At about 5:40 a.m. on December 19, 2013, 10 Burleson County deputies approached Henry Magee's trailer. They had misread the informant's directions and come from the front, not the back. They believed Magee's bedroom was on the left. It was on the right. The first flashbang went off at the wrong end of the trailer and did not immediately wake Magee or his pregnant girlfriend, Kori White (NYT, Texas raids, 2017).

After a thud at the door, Magee asked who was there. White said she heard no answer before a second thud. Magee took an AR-10 rifle from a closet. The door burst open, and an explosion followed. Magee fired toward the door. White said: "I thought we were being robbed" (NYT, Texas). She said she heard "Burleson County Sheriff's Office! Come out with your hands in the air" only after the shooting. Magee dropped the rifle and complied (NYT, Texas).

A bullet struck Investigator Adam Sowders in the head. He died (NYT, Texas).

Magee was charged with capital murder. A grand jury met for more than 12 hours, heard from every deputy involved, and declined to indict him for capital murder (NYT, Texas). Juror Jack Sullivant said: "To a one we felt he had a right to protect his home" (NYT, Texas). District Attorney Julie Renken said: "I believe the evidence also shows that an announcement was made. However, there is not enough evidence that Mr. Magee knew that day that Peace Officers were entering his home" (Techdirt, 2014). She also said: "Just because something's done legal does not mean it's done procedurally well" (NYT, Texas).

Magee pleaded guilty to felony marijuana possession and received 18 months (NYT, Texas). Sheriff Dale Stroud said the department had stopped using no-knock tactics: "It would have to be warranted under the most extreme circumstances" (NYT, Texas).

Marvin Guy, Killeen, Texas

Five months later and 85 miles away, at 5:40 a.m. on May 9, 2014, 20 Killeen officers approached Marvin Guy's ground-floor apartment (NYT, Texas). Guy, 49, had barricaded his door with an armchair after a series of break-ins in the area. He slept beside two guns. As a convicted felon, he could not legally own them (Texas Monthly, 2019).

Officers broke the bedroom windows. The battering ram opened the front door about an inch. As the entry team moved toward the back door, it passed the bedroom window. Guy said he woke to breaking glass, heard no announcement, thought he was being robbed, and fired (NYT, Texas). A detective dropped a live flashbang when he slipped on wet grass. Officers fired at least 41 rounds in a few seconds (NYT, Texas).

Detective Charles Dinwiddie, 47, a SWAT veteran of 15 years, was struck below the right eye. He died two days later. Officer Odis Denton was wounded in the thigh (NYT, Texas). State crime lab tests matched the bullets to Guy's 9mm pistol. Guy disputed the finding (NYT, Texas).

The announcement record split three ways. Eight officers said they gave notice. Fourteen said they heard others do so. Twelve did not mention an announcement. Of 65 neighbors and witnesses who heard the ram, flashbang, or gunfire, 10 said they heard shouting first (NYT, Texas). Guy told investigators: "Nobody got on the loudspeaker and said, 'This is the Police Department, come out'" (NYT, Texas).

On November 21, 2023, a jury convicted Guy of murder, not capital murder. He received a life sentence and becomes eligible for parole in 2044, at age 79 (Killeen Daily Herald). The state later dropped the remaining charges (Killeen Daily Herald).

Ray Rosas, Corpus Christi, Texas

In February 2015, Corpus Christi police raided Ray Rosas's home at night looking for his nephew. They used a flashbang. Rosas fired 15 rounds from a legally owned gun and wounded three officers. One officer was struck by a bullet fired by another officer (Texas Monthly). Rosas testified that earlier drive-by shootings had targeted his home and that the flashbang impaired his sight and hearing (Texas Monthly).

Rosas spent 664 days in jail charged with attempted capital murder. A jury acquitted him after concluding he did not know whom he was shooting at through a blinded window (NYT 2017).

Cory Maye, Prentiss, Mississippi

On December 26, 2001, police raided a duplex in Prentiss looking for another resident. Cory Maye was asleep on his side of the duplex with his 18-month-old daughter. He shot the first officer to enter his bedroom, Ron Jones, who died (Cato 2006). Whether officers announced themselves remains disputed (Wikipedia, Cory Maye).

A jury convicted Maye of capital murder, and in 2004 he was sentenced to death. Judge Michael Eubanks overturned the death sentence on September 21, 2006, for ineffective counsel at sentencing. On December 2, 2010, the Mississippi Supreme Court granted a new trial because the trial court had refused a self-defense instruction tied to his daughter's presence. On July 1, 2011, Maye pleaded guilty to manslaughter and received 10 years, credited as time served. He left custody on July 18, 2011 (Wikipedia, Cory Maye).

Other cases, other outcomes

The common features

The cases differ in many ways. The residents included a felon with illegal guns and a 92-year-old woman. Some fired first. Some never fired. The drugs ranged from a gram to a few ounces. The legal outcomes ranged from release to death row.

Five features recur.

1. The raid came in darkness or at first light. Magee and Guy were hit at 5:40 a.m. Officers broke Breonna Taylor's door at about 12:40 a.m.
2. The resident had been asleep or had just woken.
3. The entry began with breaking glass, a ram, or a flashbang, before or during any announcement.
4. The officers' accounts of an announcement conflicted with the residents' and neighbors' accounts.
5. The amount of drugs recovered was small: 4.39 ounces in Somerville, about a gram in Killeen, personal-use amounts in Houston, none in Atlanta.

A no-knock warrant guarantees the first three features. A knock-and-announce warrant served in the dark, with a short wait and a flashbang, can produce the same three.

One Texas jury convicted a man for the death of an officer under facts that a grand jury 85 miles away treated as self-defense. What the Bell County grand jurors heard remains confidential (NYT, Texas).

Who is inside

A warrant names a place and, often, a suspect. It does not empty the house of everyone else. The ACLU's review of 818 SWAT deployments found children documented as present in 14 percent. Another 35 percent of reports did not say (ACLU 2014). Many of the people killed or maimed in raids were not the person police came to find.

Aiyana Stanley-Jones, Detroit, 2010

Detroit officers raided a house looking for a murder suspect. They threw a flash grenade through a window into the living room where seven-year-old Aiyana Stanley-Jones was asleep on a couch. The device burned her blanket. Officer Joseph Weekley entered and fired a shot that killed her (ACLU 2014; CBS News, 2015). A reality television crew recorded the scene from the street (CBS News).

Weekley said he pulled the trigger accidentally during a struggle with Aiyana's grandmother. The grandmother denied touching the weapon (CBS News). Juries in 2013 and 2014 could not reach verdicts on a charge of reckless use of a firearm. The judge dismissed an involuntary manslaughter charge for insufficient evidence. On January 30, 2015, at the prosecutor's request, a judge dismissed the last charge (CBS News).

Tarika Wilson, Lima, Ohio, January 2008

Lima officers broke down Tarika Wilson's front door looking for her boyfriend on suspicion of drug dealing. An officer opened fire while Wilson held her 14-month-old son. Wilson died. The baby was wounded and survived (ACLU 2014).

Eurie Stamps, Framingham, Massachusetts, January 2011

Eurie Stamps, 68, a grandfather of 12, was in his pajamas watching baseball when a Framingham SWAT team rammed the door and threw a flashbang. Police were looking for his girlfriend's son, who did not live there and had already been arrested outside minutes earlier (ACLU 2014). Stamps followed orders and lay face down. Officer Paul Duncan's gun discharged and killed him while Stamps lay on the floor with his hands up (ACLU of Massachusetts).

On February 5, 2016, the First Circuit affirmed a lower court's denial of qualified immunity to Duncan (ACLU of Massachusetts). The town settled with the family for $3.75 million in 2016 (NYT 2017). Framingham disbanded its SWAT team (ACLU 2014).

Alberto Sepulveda, Modesto, California, September 2000

During a drug raid on September 13, 2000, an officer's shotgun discharged and killed 11-year-old Alberto Sepulveda. Officers found no drugs and no weapons in the home. The family received a $3 million settlement (Cato 2006).

Bou Bou Phonesavanh, Cornelia, Georgia, May 2014

The Phonesavanh family had moved in with relatives after their Wisconsin home burned. Two parents and four children, ages 1 to 7, slept in a converted garage (Reason 2025). Toys and a wading pool sat in the yard. A minivan in the driveway carried four child seats (Reason 2025).

At about 2:15 a.m. on May 28, 2014, 10 officers arrived in an armored Humvee to serve a no-knock warrant. Informants had bought $50 worth of methamphetamine in the front yard less than four hours earlier. Deputy Jason Stribling used the ram. Deputy Charles Long threw a flashbang about three feet into the doorway (NYT 2017). The device landed in the playpen of 19-month-old Bounkham "Bou Bou" Phonesavanh and exploded beside his face (NYT 2017).

The blast made a hole in his chest, severed his nose, and tore his lips and mouth. He spent almost a month in a medically induced coma (ProPublica, 2015). His parents said officers kept them from going to him and told them the blood in the playpen came from a lost tooth (Reason 2025). The target, Wanis Thonetheva, did not live there. He was arrested later at another address, unarmed, without a flashbang (Reason 2025). Officers found meth residue in a glass pipe and nothing else (NYT 2017).

Sheriff Joey Terrell said officers would not have used a flashbang if they had known children were inside. "The baby didn't deserve this. The family didn't deserve this" (Reason 2025). The family received $3.6 million in settlements. By late 2016 Bou Bou had undergone his 15th surgery (NYT 2017).

The local grand jury declined to indict anyone. It called the investigation "hurried" and "sloppy" (Reason 2025). It also recommended arresting suspects away from their homes when possible and reserving the "highest level of entry" for cases of absolute necessity. It wrote:

"There should be no such thing as an 'emergency' in drug investigations."

"No amount of drugs is worth a member of the public being harmed." (Reason 2025)

Others

Randall Adjessom, Mobile, Alabama, November 2023

The facts below come from body-camera video unsealed by a federal judge and from the family's pending wrongful death suit. No court has ruled on liability.

At about 5:40 a.m. on November 13, 2023, Mobile SWAT officers banged on the door of a house on Sheringham Drive and shouted "search warrant." The video shows officers entering less than five seconds later (AL.com, October 2026). They were looking for DeAngelo Adjessom, who was suspected of distributing marijuana and was not at the house (AL.com).

His brother Randall, 16, came around a hallway corner. Less than 10 seconds after the entry, an officer identified in the lawsuit as Osviel Vigoa Martinez shot him four times in the chest and abdomen. A gun lay beside him (AL.com). After the shots, an officer shouted "Hands up, hands up, hands up." Medical aid began more than four minutes later (AL.com). Randall died.

(AL.com)

Mayor Sandy Stimpson banned most predawn search warrants after the shooting and called for an independent review of police use of force. The AL.com report said Randall's death was the second fatal Mobile police shooting during a predawn raid in 2023 (AL.com).

Bou Bou Phonesavanh's medical bills passed $1 million. The county had said it would pay them, then refused (Reason 2025).

A reasonable effort

The Supreme Court does not require officers to be right about the address. In Maryland v. Garrison (1987), the Court held that a mistaken search does not violate the Fourth Amendment when officers make "a reasonable effort to ascertain and identify the place intended to be searched" (Norris v. Williams, 11th Cir. 2021, discussing Garrison). The rule asks for effort, not accuracy.

Wrong-address raids carry a specific danger. The people inside have done nothing that would lead them to expect police. When strangers break the door at night, the residents have no basis for assuming the intruders are police.

How often

No national count exists. Two New York figures give a sense of scale.

• Police Commissioner Raymond Kelly estimated that at least 10 percent of the more than 450 no-knock drug raids New York police conducted each month went to the wrong address, rested on bad information, or otherwise failed to justify an arrest (Cato 2006).
• The Council on Criminal Justice reported that about 10 percent of New York Police Department raids in 2003 occurred at the wrong location (CCJ).

A Los Angeles officer told the New York Times in 1973 that erroneous raids happened "once or twice a month" (NYT 1973).

Alberta Spruill, Harlem, May 16, 2003

New York police raided Alberta Spruill's Harlem apartment on an uncorroborated tip and threw a flashbang. Spruill, 57, suffered cardiac arrest and died. The suspected dealer was already in police custody (Cato 2006).

The city responded. A review board hotline received more than 100 calls in its first week from people reporting wrong no-knock raids. New procedures lengthened the time needed to obtain a warrant from two hours to 24. Drug raids fell from 5,117 in 2002 to 3,577 in 2003 (Cato 2006).

Ismael Mena, Denver, September 29, 1999

Denver police raided the wrong house on an informant's error and killed Ismael Mena. Police said he fired first. His family said police did not announce themselves and fired first. Officers found no drugs. An internal investigation found that the officer who swore out the warrant had falsified information. The city settled for $400,000 (Cato 2006).

Mario Paz, El Monte, California, August 9, 1999

Police shot and killed Mario Paz, 65, during a mistaken raid. He was unarmed when shot. Police found no evidence that his family was involved in drugs but initially sought to forfeit more than $10,000 found in the home. The city settled for $3 million in 2002 (Cato 2006).

Karen Jimerson, Waxahachie, Texas

A Drug Enforcement Administration officer gave Waxahachie Police Lieutenant Mike Lewis a warrant, a description, and photographs of the target house at 573 8th Street. The caravan stopped at 583. The target sat to the officers' right. Karen Jimerson's home at 593 sat to their left (Institute for Justice).

Lewis ordered a "break and rake" on Jimerson's house. A break and rake means breaking windows and raking out the glass so officers can see and aim inside. Officers broke down the front door, shattered windows over her sleeping children, and set off a flashbang in the yard (Institute for Justice). Jimerson's house had a wheelchair ramp. The target had a porch, a detached garage, a fence, and its number painted on the curb. Jimerson's number, 593, was fixed to the front of her house (Institute for Justice). The team held the family at gunpoint until an officer shouted "Wrong house!"

The police chief testified that mistakes like this "should never happen." An internal investigation found that "reasonable and normal [Department] protocol was completely overlooked." Lewis received a two-day unpaid suspension (Institute for Justice). Lewis conceded that the raid violated the Fourth Amendment. A divided Fifth Circuit panel still granted him qualified immunity, 2 to 1, holding that he lacked "fair notice" because he had done more than "nothing" to identify the house (Institute for Justice).

Onree Norris, McDonough, Georgia, February 8, 2018

More than 24 officers from a drug task force and the Henry County Sheriff's Office Special Response Team went to serve a no-knock warrant at 305 English Road. The target, Gemar Watkins, had a violent reputation (Norris, 11th Cir.). The house at 305 turned out to be dilapidated, with no windows, doors, or electricity. Team leaders concluded it could not be the target. They moved about 40 yards to the next house, a lighted yellow home at 303 English Road, threw two more flash grenades, and forced entry (Norris).

The house belonged to Onree Norris. The entire sequence took about a minute and a half. Task force agents then told the team it had raided the wrong house (Norris). On May 5, 2021, the Eleventh Circuit affirmed qualified immunity for the team commander. The court did not hold the entry lawful. It held that prior cases had not clearly established that the commander's conduct was unconstitutional, and it called the raid "no doubt traumatic" (Norris).

Qualified immunity

Qualified immunity shields government officials from civil damages unless they violated a constitutional right that was "clearly established" by earlier cases with similar facts. The doctrine explains why Jimerson and Norris, whose homes were raided by mistake, could not recover damages from the officers who led the raids. Chapter 13 returns to the doctrine.

More wrong doors

Remy said officers "didn't even do a simple address search to see that the property had transferred" (AP via PennLive). Columbus now requires at least two hours of surveillance before a no-knock warrant is served. In the first months under the ordinance, the police chief received two no-knock requests and denied both (AP via PennLive).

Karen Jimerson's house number, 593, differed from the warrant's 573 by one digit (Institute for Justice).

The device

A flashbang, also called a stun grenade or distraction device, is a canister that produces a bright flash, a deafening blast, and smoke. The ACLU reported that the flash can cause temporary blindness lasting 5 to 10 seconds, along with disorientation and ringing in the ears (ACLU 2014). Police generally classify the device as nonlethal. It has started fires and caused heart attacks, some fatal (ACLU 2014).

Tactical teams use flashbangs to stun the people inside during the first seconds of an entry. The device serves the same purpose as the no-knock warrant: to take the occupants by surprise. It works the same way under either kind of warrant.

How often teams use them

Little Rock police spokesman Sidney Allen defended the practice. "What we see is a large service of warrants without gunfire," he said. In 2012, Little Rock officers battered the door of Sharon Kay Harris and threw flashbangs into her kitchen and living room over alleged unlicensed food and Sunday liquor sales, both misdemeanors. Harris was fined $950. Of that raid, Allen said: "What you call extreme, we call safe" (ProPublica).

Injuries

ProPublica found in 2015 that at least 50 Americans, including police officers, had been seriously injured, maimed, or killed by flashbangs since 2000. The news organization called that figure likely a fraction of the total because few departments keep deployment records (ProPublica).

Treneshia Dukes

Before dawn on July 21, 2010, 18 officers arrived at the Laurel Park apartments in Clayton County, Georgia, looking for a 22-year-old man suspected of having a small amount of marijuana. They broke the bedroom window in a break and rake and breached the front door. They used at least three flashbangs (ProPublica).

Dukes testified that a round object flew through the bedroom window, landed on her thigh, and exploded. Two witnesses described black residue on the wall above the bed. A burned comforter survived as evidence (ProPublica). SWAT commander Stephen Branham testified: "Nobody threw a bang through that window." Sgt. Scott Malette said he threw the device into the front hallway and that Dukes must have run into it (ProPublica). The point of impact remained disputed.

County records showed no flashbang training in the three years before the raid. Officers testified that general SWAT training included flashbangs, though logs did not record it (ProPublica). Malette also described a 2009 raid in which a flashbang landed on a bed and burned a sleeping man's legs. His report read: "The room was dark, and I did not identify any room occupants" (ProPublica). An internal investigation found officers had done "nothing wrong" in the Dukes raid (ProPublica).

Rules

ProPublica found no binding national training standard for flashbangs. Departments registered their stock with the Bureau of Alcohol, Tobacco, Firearms and Explosives. ProPublica found no federal rule on how or when to use the devices (ProPublica). The National Tactical Officers Association advised that untrained officers should not use the devices (ProPublica).

Courts have set some limits. A 1987 California Supreme Court ruling treated a flashbang as reasonable force when officers "have seen fully into a targeted room." In 2000 the Seventh Circuit wrote: "police cannot automatically throw bombs into drug dealers' houses, even if the bomb goes by the euphemism 'flash-bang device'" (ProPublica). ProPublica found no criminal conviction of any officer for injuring a civilian with a flashbang (ProPublica).

Some statutes now address the devices. Maine allows only officers trained on "stun grenade, stun, distraction or other similar devices" to use them during a no-knock entry (Maine § 57).

The flashbang and the warrant

A ban on no-knock warrants does not ban flashbangs. Georgia State Senator Vincent Fort pushed for a higher no-knock standard beginning in 2008. ProPublica noted that a stricter no-knock rule would not necessarily stop police from using flashbangs after a brief knock (ProPublica). The Knox County lawsuit over the January 2025 death of Daevon Saint-Germain, covered in Chapter 12, alleges a flashbang entry in a state that had already banned no-knock warrants (Atlanta Black Star, 2026).

Deputy Charles Long violated protocol in Cornelia by failing to light the room before he threw the device (Reason 2025).

Three cases, three stages

Three deaths between 2020 and 2025 show the no-knock question at three stages of the legal process. The Louisville case has produced convictions, dismissals, and settlements, with charges still pending. The Minneapolis case ended with a decision not to charge and a civil suit still open. The Knoxville case has an open lawsuit and few public facts.

Breonna Taylor, Louisville, March 13, 2020

The warrant

Detective Joshua Jaynes sought warrants for five addresses tied to Jamarcus Glover, Breonna Taylor's former boyfriend, whom police suspected of selling drugs (Mississippi Today; Reason 2025). Jefferson Circuit Judge Mary Shaw signed a no-knock warrant for Taylor's apartment (Wikipedia, Killing of Breonna Taylor). Reports indicate that officers were told before the raid to knock and announce instead (Wikipedia).

Jaynes later admitted he had not personally verified with a postal inspector that Glover received packages at Taylor's address, as the affidavit claimed. A postal inspector said nothing about the packages was suspicious (Reason 2025).

The entry

At about 12:40 a.m., three plainclothes officers banged on the door and then broke it open with a ram. The officers said they announced themselves. Nearly all of Taylor's neighbors contradicted that account (Reason 2025). Kenneth Walker, Taylor's boyfriend, said he heard no announcement and did not know the intruders were police. He fired one shot from his legally owned handgun and hit Sgt. Jonathan Mattingly in the thigh (Reason 2025).

Officers fired 32 rounds. Mattingly fired six, Detective Myles Cosgrove 16, and Detective Brett Hankison 10. Hankison fired blindly through a covered bedroom window and a covered sliding glass door (Reason 2025). Taylor, 26, an emergency medical technician, was unarmed in a dark hallway. Bullets struck her several times; investigators concluded that Cosgrove fired the fatal shot (Reason 2025). No drugs were found in the apartment (Wikipedia).

What followed

The 2023 Justice Department report found that Louisville officers "executed no-knock warrants far more often than they applied for them." Some officers whispered or announced quietly before shouting "Police! Search warrant!" and entering. Officers rarely recorded warrant service on body cameras (LPM).

Hankison told the federal court he would have acted differently had he known of the warrant's problems: "I never would have fired my gun" (Reuters). Judge Rebecca Grady Jennings imposed the sentence at the low end of the guideline range of 33 to 41 months. She said: "This sentence cannot and will not be compared to Ms. Taylor's life and the overall incident" (Reuters).

The pending case against Jaynes and Meany

The prosecution of Jaynes and Meany remains open.

Simpson also wrote that he was "seriously troubled by the claimed falsehoods which root the charges in this case" (Courier-Journal).

Amir Locke, Minneapolis, February 2, 2022

The facts

Minneapolis SWAT officers served a no-knock warrant for St. Paul police at an apartment in the Bolero Flats building downtown. The warrant related to the January killing of Otis Elder. Amir Locke, 22, was not named in the warrant and was not a suspect (CBS Minnesota, 2022).

Body-camera video shows an officer unlock the door with a key. Officers entered and shouted "police" and "search warrant." Locke had been asleep on a couch under a blanket. He sat up holding a handgun. Officer Mark Hanneman shot him three times. About nine to 10 seconds passed between the entry and the shots (CBS Minnesota; MPR News). Locke died minutes later.

The charging decision

On April 6, 2022, Hennepin County Attorney Mike Freeman and Attorney General Keith Ellison declined to charge Hanneman. Their 44-page report found that a reasonable officer in his position would have perceived an "immediate threat of death or great bodily harm" (CBS Minnesota). They said it was not their role to judge whether the no-knock warrant was appropriate. Their joint statement added: "This tragedy may not have occurred absent the no-knock warrant used in this case" (CBS Minnesota).

Ellison said: "One thing Amir was not, Amir was not a suspect." He said no-knock warrants were "not particularly safe for officers, either" (CBS Minnesota).

Open questions

Locke's family sued the city. A federal judge denied the city's motion to dismiss on July 9, 2024, and an appeals court allowed the wrongful death claim against Hanneman to proceed on July 21, 2025 (MPR News). No court has ruled on liability. The suit is pending.

The policy aftermath

Mayor Jacob Frey had said during his 2021 campaign that he had banned no-knock warrants. The city policy then in effect allowed them for an "imminent threat of harm." Frey later said: "Language became more casual, including my own, which did not reflect the necessary precision or nuance. And I own that" (CBS Minnesota). Minneapolis adopted a new policy in 2022 (CBS Minnesota).

Minnesota restricted no-knock warrants by statute in 2023. MPR News reported 179 no-knock warrants issued before the change, 84 in 2023, and 18 issued and 16 executed in 2024 (MPR News, August 12, 2025).

Daevon Saint-Germain, Knox County, Tennessee, January 3, 2025

The facts below come from the family's lawsuit, the sheriff's office, and news reports. The case is pending. No court has made findings.

Crump said: "He was killed as a result of a no-knock warrant. Not just a no-knock warrant, but a flashbang no-knock warrant" (Atlanta Black Star). The sheriff's office has not described the warrant that way in the sources reviewed.

The lawsuit names the deputies as John and Jane Doe (Atlanta Black Star).

Three remedies

A person harmed by an unlawful entry has three possible remedies.

1. Suppression. A court excludes the evidence the police found. Hudson v. Michigan (2006) removed suppression as a remedy for knock-and-announce violations (Hudson).
2. Criminal prosecution of the officers.
3. A civil lawsuit for damages against the officers or the government that employs them.

Justice Stephen Breyer wrote in his Hudson dissent that the decision "destroys the strongest legal incentive to comply with the Constitution's knock-and-announce requirement" (Breyer dissent). The majority answered that civil suits and growing police professionalism would deter violations (Hudson). Chapter 3 covers that exchange.

Prosecutions

The New York Times reported in 2017 that in almost all of the botched raids it examined, prosecutors declined to charge the officers involved (NYT 2017). The cases below are the exceptions, plus several in which charges failed.

Two features stand out. First, the cases that produced prison time involved lies on paper: an invented informant in Houston, a planted bag of marijuana in Atlanta, a false postal claim in Louisville. Prosecutors charged the paperwork more readily than the shooting. Second, the officers who fired the fatal shots were rarely the ones convicted. Investigators concluded that Cosgrove fired the fatal shot at Taylor. Hankison, the officer convicted, fired blindly through covered windows (Reason 2025).

The Goines fallout

The Harding Street investigation reached far past one raid. Harris County District Attorney Kim Ogg's office reexamined about 1,400 drug cases involving Goines and described his conduct as a "pattern of deceit" going back more than a decade. The Associated Press reported that the Texas Court of Criminal Appeals had overturned at least 22 convictions linked to him (Reason 2024). Goines had obtained nearly 100 no-knock warrants over 12 years (Reason 2025).

Civil suits

The Times counted an average of at least 30 federal civil rights lawsuits a year from 2010 to 2015 over residential warrants served with dynamic entry. At least seven had settled for more than $1 million in the previous five years (NYT 2017).

The Phonesavanh family had spent all but $200,000 of its settlement on medical and legal bills by the time the Times reported on the case (NYT 2017).

Qualified immunity

Qualified immunity protects officers from personal liability unless prior court decisions "clearly established" that the specific conduct was unconstitutional. Courts have applied the doctrine in several no-knock cases.

The Norris and Jimerson rulings did not find the raids lawful. Each found that no earlier case was close enough on its facts to have warned the officer. Under the doctrine, an officer whose conduct has no close precedent can avoid personal liability.

Discipline

Internal discipline varied as much as the courts did. Louisville fired Cosgrove and Jaynes in 2020 (Reason 2025). Waxahachie suspended Lt. Lewis for two days without pay (Institute for Justice). Clayton County found officers had done "nothing wrong" in the Treneshia Dukes raid (ProPublica). ProPublica found no criminal conviction of an officer for a flashbang injury (ProPublica).

Goines must serve 35 months of his federal sentence after credit for time served. He was already serving his 60-year state term for murder (CW39).

Before 2020

A few states limited no-knock warrants long before Louisville.

• Oregon. State law requires officers to give notice of identity, authority, and purpose before entering. A magistrate has no authority to waive the requirement (Georgia Senate 50-state survey, 2020).
• Florida. The Florida Supreme Court held in State v. Bamber (1994) that a no-knock warrant has no legal effect without express statutory authorization, and the legislature had given none. Officers may still enter without announcing in exigent circumstances (Georgia Senate survey).
• Utah. Utah barred no-knock warrants based solely on drug possession or use (CCJ; Georgia Senate survey). The state later added detailed requirements, described below.

After Breonna Taylor

The Council on Criminal Justice counted bills and ordinances to ban or restrict no-knock warrants in 22 states and 20 cities as of January 2021. Fifteen cities had passed bans or severe restrictions, including Orlando, Louisville, Santa Fe, and Indianapolis (CCJ).

Maryland's 2026 fiscal note counted six states that had banned no-knock warrants since 2021: Connecticut, Florida, Oregon, Tennessee, Virginia, and Washington. Maine, Nevada, and Utah limited them to exigent circumstances (HB 464 fiscal note).

Kentucky's law drew criticism from both directions. State Rep. Attica Scott, who had sponsored a full ban, voted for the bill and said: "It gets us closer to justice, but this ain't it" (NPR). In Virginia, Republican Sen. Ryan McDougle opposed his state's bill as "too broad" and objected to the daytime limit: "Crime does not stop just because the sun goes down" (AP via PennLive). Del. Lashrecse Aird had proposed a 30-second wait after knocking. That provision did not survive negotiations (AP via PennLive).

What the counts show after the laws

Minnesota and Maryland publish numbers.

The Minnesota Bureau of Criminal Apprehension reported a 79 percent drop in the first full year under the law (MPR News). Neither series shows whether deaths or injuries fell. The numbers are too small and the reporting too recent. Maryland's fiscal note said the state lacked the demographic data to assess the effect of a full ban on racial groups (HB 464 fiscal note). No published study has measured the effect of any ban on deaths, injuries, or evidence recovery.

Maryland's HB 464, introduced in the 2026 session, would repeal the authority to issue no-knock warrants and require "reasonable notice" before any search warrant is served (HB 464 fiscal note).

Federal policy, 2021 to 2026

Blanche's memo said: "We must allow our brave men and women in law enforcement to carry out their duties to the fullest extent permitted by law" (MS NOW). Former prosecutors told MS NOW that the risk of evidence destruction could be argued in nearly every search. Vanita Gupta, a former associate attorney general, called the reversal "a step backwards for policing" (MS NOW).

The 2026 federal rule returned to the evidence-destruction ground that Congress attached to the 1970 federal no-knock statute and repealed in 1974 (Chapter 2).

Cities and voters

Local action continued after the federal reversal.

• Houston. The police department banned no-knock warrants after the Harding Street raid. On November 3, 2026, voters approved Proposition A by more than 70 percent in unofficial results. The charter amendment prohibits Houston officers from "requesting or executing 'no-knock' search warrants." Ground Game Texas gathered more than 40,000 signatures to place the measure on the ballot (Houston Public Media).
• Dallas and San Marcos. Similar measures passed and drew legal challenges from Texas Attorney General Ken Paxton (Houston Public Media).
• Mobile, Alabama. Mayor Sandy Stimpson banned most predawn search warrants after the November 2023 death of Randall Adjessom (AL.com).
• Columbus, Ohio. An ordinance requires at least two hours of surveillance and the chief's approval before a no-knock warrant (AP via PennLive).
• Georgia. Statewide bills in 2015 (SB 159) and 2020 (SB 513) did not pass (Georgia Senate survey).

The quick-knock problem

Peter Kraska of Eastern Kentucky University warned in 2020 that bans could leave a loophole for "quick-knock" entries, in which officers knock and then enter at once (AP via PennLive). The Council on Criminal Justice wrote that the 15-to-20-second wait approved in United States v. Banks "blurs the legal line between no-knock warrants and standard knock warrants" (CCJ). Even where no-knock warrants are banned, officers may still enter without announcing in an emergency (CCJ).

Houston voters approved the charter amendment about seven years after Dennis Tuttle and Rhogena Nicholas died at 7815 Harding Street (Houston Public Media; Reason 2024).

The problem stated plainly

Every warrant service balances three risks: harm to officers, harm to the people inside, and loss of evidence. Police who choose a no-knock warrant accept a higher risk of violent confusion in exchange for a lower risk that drugs go down the toilet. Departments that stopped using no-knock warrants did not stop serving warrants. They changed how they served them.

Arrest the person away from the house

Researchers led by Brandon del Pozo interviewed narcotics officers in January and February 2022 at a large Midwestern department that serves about one million residents. The department had shifted away from no-knock drug warrants in early 2020 (del Pozo et al.). The officers described two methods that replaced the old raids.

1. Wait for the suspect to leave, make what looks like a routine traffic stop, take the person into custody, and return to the house with more information about who and what is inside.
2. If the first method is not possible, ask SWAT to serve the warrant with a knock and announcement.

One officer said: "We breach if we have to, but we give [the suspect] plenty of time" (del Pozo et al.). The Habersham County grand jury that reviewed the Bou Bou Phonesavanh raid made the same recommendation in 2014: arrest suspects away from their homes when possible and reserve the "highest level of entry" for cases of absolute necessity (Reason 2025).

What officers said about safety and evidence

All but one of the six officers in the del Pozo study believed ending no-knock drug warrants made both officers and civilians safer. One said: "most of the shootings we've gotten into was on no-knock search warrants." The dissenting officer said no-knock entry let officers take control before someone could "think or grab a gun." He also said, "I haven't looked at the [shooting] numbers" (del Pozo et al.).

Evidence loss was the main cost. One officer said that under knock-and-announce, "if there's any evidence in the house other than a gun, it's going down the toilet." Another answered: "Well, they can't flush their guns!" A third said officers should "have your case made before you go in" (del Pozo et al.). The authors found the change feasible and acceptable in that department. They also found it increased reliance on SWAT, because narcotics units handed warrant service to the tactical team (del Pozo et al.). The study covered one department and six officers.

Practices in current law and policy

The measures below appear in statutes, policies, or recommendations already in use. The right column links each practice to a failure documented in earlier chapters.

The Council on Criminal Justice recommendations

The Council on Criminal Justice's 2021 review recommended:

• Prohibiting or severely restricting no-knock warrants, unannounced raids, and quick-knock warrants.
• Limiting raids of occupied homes to clear and present danger, such as hostage situations, supported by verified intelligence.
• Assessing and documenting the claimed emergency before service and again at the scene.
• Restricting nighttime service of standard warrants to emergencies.
• Publishing annual data on warrant requests, service, and outcomes.
• Recording the premises on video before and after searches.
• Compensating owners for damage when police find no contraband and arrest no one (CCJ).

The council acknowledged that fewer forcible entries may mean more destroyed evidence. It judged the public-safety gains from such entries small compared with the risks of serious injury, death, and lost legitimacy (CCJ).

The case against bans

Police organizations raised objections that deserve a direct answer.

• Thor Eells, executive director of the National Tactical Officers Association, said in 2020: "At the end of the day, any kind of warrant service tends to be dangerous, period." He said his association had concluded no-knock entry was not necessarily the safest way to serve warrants, yet he called an outright ban a "knee-jerk reaction." Asked whether to ban them, he said: "The answer is categorically no" (AP via PennLive).
• Wayne Huggins of the Virginia State Police Association said: "The element of surprise is one of the best tools." He said officers who must knock and announce have "given up the element of surprise" (AP via PennLive).
• Virginia Sen. Ryan McDougle argued that daytime limits might put officers at risk and give suspects time to dispose of evidence (AP via PennLive).
• Peter Kraska, an Eastern Kentucky University professor who studies police paramilitary units, said unannounced entry could be essential in some situations, such as an active shooter (AP via PennLive).

These objections carry weight. Surprise has real tactical value. Some entries, such as hostage rescues, cannot wait. The Council on Criminal Justice noted that officers may still enter without warning in exigent circumstances where no-knock warrants are banned (CCJ). The question the reform states answered was narrower: whether a judge should approve unannounced entry in advance, often for drug cases, often at night.

What the record does not show

The Council on Criminal Justice found in 2021 that no study had examined whether banning no-knock warrants reduces deaths or injuries (CCJ). Two randomized experiments, in Kansas City and Buffalo, found that raids had no significant effect on serious violent crime (CCJ). A study of Maryland and of about 9,000 agencies found no significant effect of SWAT teams on crime or on assaults against officers (CCJ; Mummolo).

The first replacement method the del Pozo officers described was a traffic stop on a suspect who had driven away from the house (del Pozo et al.).

The question at the start

A common belief holds that no-knock warrants end in violence more often than other warrants. The record supports part of that premise, contradicts part of it, and leaves part of it unmeasured.

What the record supports

• Officers die at a higher share in no-knock raids. In the New York Times count for 2010 to 2016, officers made up about 20 percent of deaths in no-knock raids and about 10 percent in knock-and-announce raids. Eight officers died in no-knock raids and five in knock-and-announce raids (NYT 2017; CCJ).
• No-knock raids probably account for more than their share of deaths. No national count of raids exists. Using Utah and Columbus figures as a rough guide, no-knock warrants made up about 25 to 40 percent of tactical warrant service, yet no-knock raids produced about 40 percent of known-type civilian deaths and about 62 percent of officer deaths (Chapter 6). The estimate rests on stacked assumptions.
• Armed residents who mistake police for criminals are a recurring feature of fatal no-knock raids. Henry Magee, Marvin Guy, Cory Maye, Kathryn Johnston, Dennis Tuttle, Kenneth Walker, and Amir Locke all reached for or fired a gun at people who had entered without warning or with a warning they said they never heard (Chapters 8, 12).
• Many no-knock warrants rest on thin or false paper. Goines invented an informant. The Cornelia affidavit named the wrong informant. Mississippi judges signed boilerplate (Chapter 7).
• Wrong-door raids happen at a measurable rate. New York police estimated about 10 percent of raids in 2003 went to the wrong location or rested on bad information (CCJ; Cato 2006).

What the record contradicts

• Knock-and-announce raids are not safe. Forty-seven of the 81 civilians in the Times count died in knock-and-announce raids (NYT 2017). A knock followed by an entry within seconds, at night, by people the resident cannot see, carries many of the same dangers. The Council on Criminal Justice recommended restricting quick-knock warrants for that reason (CCJ).
• The label does not settle what happened at the door. In Louisville, a judge signed a no-knock warrant, officers said they knocked, and nearly all neighbors said they heard nothing (Reason 2025). The Justice Department found Louisville officers "executed no-knock warrants far more often than they applied for them" (LPM).

What remains unmeasured

• The number of no-knock and knock-and-announce warrants served nationally each year. The Center for Justice Research cited an estimate of 20,000 to 80,000 no-knock warrants a year (CJR). The range spans a factor of four.
• Death and injury rates per raid for each warrant type.
• Whether the higher officer share reflects the entry method or the selection of more dangerous targets (Chapter 6).
• Whether any ban has reduced deaths or injuries. No study had examined that question as of 2021 (CCJ).
• Whether the 2026 federal reversal will change the number of no-knock entries by federal agents (MS NOW).

The common factor

Most of the fatal cases in these chapters share the same elements: a forced entry, a sleeping household, darkness or near darkness, plainclothes or unidentifiable officers, little or no warning, and a resident who has a gun or a reason to fear one. A no-knock warrant authorizes that combination in advance. A quick-knock entry at 2 a.m. can produce the same combination. A daytime knock-and-announce service by uniformed officers removes several of its elements.

Judges, legislators, and police chiefs control most of the elements in that sequence. Several states have already acted on the timing, uniforms, cameras, waiting periods, approvals, and address checks described in Chapter 15. The federal government moved in both directions between 2021 and 2026.

Neal Street

In August 2018, the Atlanta City Council announced plans to name a park for Kathryn Johnston. Kathryn Johnston Memorial Park sits a few blocks from the Neal Street house where officers killed her in 2006, at 92, during a no-knock raid built on a false informant claim. The park has greenspace, fitness stations, and a playground (Atlanta Journal-Constitution).
