OFF THE WIRE
Is it time to reconsider the militarization of American policing?
On Jan. 4 of last year, a local narcotics strike force conducted a 
raid on the Ogden, Utah, home of Matthew David Stewart at 8:40 p.m. The 
12 officers were acting on a tip from Mr. Stewart's former girlfriend, 
who said that he was growing marijuana in his basement. Mr. Stewart 
awoke, naked, to the sound of a battering ram taking down his door. 
Thinking that he was being invaded by criminals, as he later claimed, he
 grabbed his 9-millimeter Beretta pistol. 
The police say that they knocked and 
identified themselves, though Mr. Stewart and his neighbors said they 
heard no such announcement. Mr. Stewart fired 31 rounds, the police more
 than 250. Six of the officers were wounded, and Officer Jared Francom 
was killed. Mr. Stewart himself was shot twice before he was arrested. 
He was charged with several crimes, including the murder of Officer 
Francom.
The police found 16 small marijuana plants in Mr. Stewart's basement.
 There was no evidence that Mr. Stewart, a U.S. military veteran with no
 prior criminal record, was selling marijuana. Mr. Stewart's father said
 that his son suffered from post-traumatic stress disorder and may have 
smoked the marijuana to self-medicate.
Early this year, the Ogden city 
council heard complaints from dozens of citizens about the way drug 
warrants are served in the city. As for Mr. Stewart, his trial was 
scheduled for next April, and prosecutors were seeking the death 
penalty. But after losing a hearing last May on the legality of the 
search warrant, Mr. Stewart hanged himself in his jail cell. 
The police tactics at issue in the Stewart case are no anomaly. Since
 the 1960s, in response to a range of perceived threats, law-enforcement
 agencies across the U.S., at every level of government, have been 
blurring the line between police officer and soldier. Driven by martial 
rhetoric and the availability of military-style equipment—from bayonets 
and M-16 rifles to armored personnel carriers—American police forces 
have often adopted a mind-set previously reserved for the battlefield. 
The war on drugs and, more recently, post-9/11 antiterrorism efforts 
have created a new figure on the U.S. scene: the warrior cop—armed to 
the teeth, ready to deal harshly with targeted wrongdoers, and a growing
 threat to familiar American liberties.
The acronym SWAT stands for Special 
Weapons and Tactics. Such police units are trained in methods similar to
 those used by the special forces in the military. They learn to break 
into homes with battering rams and to use incendiary devices called 
flashbang grenades, which are designed to blind and deafen anyone 
nearby. Their usual aim is to "clear" a building—that is, to remove any 
threats and distractions (including pets) and to subdue the occupants as
 quickly as possible.
 The country's first official SWAT team started in the late 1960s in 
Los Angeles. By 1975, there were approximately 500 such units. Today, 
there are thousands. According to surveys conducted by the criminologist
 Peter Kraska of Eastern Kentucky University, just 13% of towns between 
25,000 and 50,000 people had a SWAT team in 1983. By 2005, the figure 
was up to 80%.
The number of raids conducted by 
SWAT-like police units has grown accordingly. In the 1970s, there were 
just a few hundred a year; by the early 1980s, there were some 3,000 a 
year. In 2005 (the last year for which Dr. Kraska collected data), there
 were approximately 50,000 raids.
A number of federal agencies also now 
have their own SWAT teams, including the Fish & Wildlife Service, 
NASA and the Department of the Interior. In 2011, the Department of 
Education's SWAT team bungled a raid on a woman who was initially 
reported to be under investigation for not paying her student loans, 
though the agency later said she was suspected of defrauding the federal
 student loan program. 
The details of the case aside, the 
story generated headlines because of the revelation that the Department 
of Education had such a unit. None of these federal departments has 
responded to my requests for information about why they consider such 
high-powered military-style teams necessary. 
Americans have long been wary of using
 the military for domestic policing. Concerns about potential abuse date
 back to the creation of the Constitution, when the founders worried 
about standing armies and the intimidation of the people at large by an 
overzealous executive, who might choose to follow the unhappy precedents
 set by Europe's emperors and monarchs.
The idea for the first SWAT team in 
Los Angeles arose during the domestic strife and civil unrest of the 
mid-1960s. Daryl Gates, then an inspector with the Los Angeles Police 
Department, had grown frustrated with his department's inability to 
respond effectively to incidents like the 1965 Watts riots. So his 
thoughts turned to the military. He was drawn in particular to Marine 
Special Forces and began to envision an elite group of police officers 
who could respond in a similar manner to dangerous domestic 
disturbances.
Mr. Gates initially had difficulty getting his idea accepted. Los 
Angeles Police Chief William Parker thought the concept risked a breach 
in the divide between the military and law enforcement. But with the 
arrival of a new chief, Thomas Reddin, in 1966, Mr. Gates got the green 
light to start training a unit. By 1969, his SWAT team was ready for its
 maiden raid against a holdout cell of the Black Panthers.
At about the same time, President 
Richard Nixon was declaring war on drugs. Among the new, tough-minded 
law-enforcement measures included in this campaign was the no-knock 
raid—a policy that allowed drug cops to break into homes without the 
traditional knock and announcement. After fierce debate, Congress passed
 a bill authorizing no-knock raids for federal narcotics agents in 1970.
 
Over the next several years, stories 
emerged of federal agents breaking down the doors of private homes 
(often without a warrant) and terrorizing innocent citizens and 
families. Congress repealed the no-knock law in 1974, but the policy 
would soon make a comeback (without congressional authorization). 
During the Reagan administration, 
SWAT-team methods converged with the drug war. By the end of the 1980s, 
joint task forces brought together police officers and soldiers for drug
 interdiction. National Guard helicopters and U-2 spy planes flew the 
California skies in search of marijuana plants. When suspects were 
identified, battle-clad troops from the National Guard, the DEA and 
other federal and local law enforcement agencies would swoop in to 
eradicate the plants and capture the people growing them. 
Advocates of these tactics said that 
drug dealers were acquiring ever bigger weapons and the police needed to
 stay a step ahead in the arms race. There were indeed a few 
high-profile incidents in which police were outgunned, but no data exist
 suggesting that it was a widespread problem. A study done in 1991 by 
the libertarian-leaning Independence Institute found that less than 
one-eighth of 1% of homicides in the U.S. were committed with a 
military-grade weapon. Subsequent studies by the Justice Department in 
1995 and the National Institute for Justice in 2004 came to similar 
conclusions: The overwhelming majority of serious crimes are committed 
with handguns, and not particularly powerful ones.
The new century brought the war on 
terror and, with it, new rationales and new resources for militarizing 
police forces. According to the Center for Investigative Reporting, the 
Department of Homeland Security has handed out $35 billion in grants 
since its creation in 2002, with much of the money going to purchase 
military gear such as armored personnel carriers. In 2011 alone, a 
Pentagon program for bolstering the capabilities of local law 
enforcement gave away $500 million of equipment, an all-time high.
The past decade also has seen an alarming degree of mission creep for
 U.S. SWAT teams. When the craze for poker kicked into high gear, a 
number of police departments responded by deploying SWAT teams to raid 
games in garages, basements and VFW halls where illegal gambling was 
suspected. According to news reports and conversations with poker 
organizations, there have been dozens of these raids, in cities such as 
Baltimore, Charleston, S.C., and Dallas. 
In 2006, 38-year-old optometrist Sal 
Culosi was shot and killed by a Fairfax County, Va., SWAT officer. The 
investigation began when an undercover detective overheard Mr. Culosi 
wagering on college football games with some buddies at a bar. The 
department sent a SWAT team after Mr. Culosi, who had no prior criminal 
record or any history of violence. As the SWAT team descended, one 
officer fired a single bullet that pierced Mr. Culosi's heart. The 
police say that the shot was an accident. Mr. Culosi's family suspects 
the officer saw Mr. Culosi reaching for his cellphone and thought he had
 a gun.
Assault-style raids have even been 
used in recent years to enforce regulatory law. Armed federal agents 
from the Fish & Wildlife Service raided the floor of the Gibson 
Guitar factory in Nashville in 2009, on suspicion of using hardwoods 
that had been illegally harvested in Madagascar. Gibson settled in 2012,
 paying a $300,000 fine and admitting to violating the Lacey Act. In 
2010, the police department in New Haven, Conn., sent its SWAT team to 
raid a bar where police believed there was underage drinking. For sheer 
absurdity, it is hard to beat the 2006 story about the Tibetan monks who
 had overstayed their visas while visiting America on a peace mission. 
In Iowa, the hapless holy men were apprehended by a SWAT team in full 
gear.
Unfortunately, the activities of 
aggressive, heavily armed SWAT units often result in needless bloodshed:
 Innocent bystanders have lost their lives and so, too, have police 
officers who were thought to be assailants and were fired on, as 
(allegedly) in the case of Matthew David Stewart.
In my own research, I have collected 
over 50 examples in which innocent people were killed in raids to 
enforce warrants for crimes that are either nonviolent or consensual 
(that is, crimes such as drug use or gambling, in which all parties 
participate voluntarily). These victims were bystanders, or the police 
later found no evidence of the crime for which the victim was being 
investigated. They include Katherine Johnston, a 92-year-old woman 
killed by an Atlanta narcotics team acting on a bad tip from an 
informant in 2006; Alberto Sepulveda, an 11-year-old accidentally shot 
by a California SWAT officer during a 2000 drug raid; and Eurie Stamps, 
killed in a 2011 raid on his home in Framingham, Mass., when an officer 
says his gun mistakenly discharged. Mr. Stamps wasn't a suspect in the 
investigation. 
What would it take to dial back such 
excessive police measures? The obvious place to start would be ending 
the federal grants that encourage police forces to acquire gear that is 
more appropriate for the battlefield. Beyond that, it is crucial to 
change the culture of militarization in American law enforcement. 
Consider today's police recruitment 
videos (widely available on YouTube), which often feature cops 
rappelling from helicopters, shooting big guns, kicking down doors and 
tackling suspects. Such campaigns embody an American policing culture 
that has become too isolated, confrontational and militaristic, and they
 tend to attract recruits for the wrong reasons.  
If you browse online police discussion
 boards, or chat with younger cops today, you will often encounter some 
version of the phrase, "Whatever I need to do to get home safe." It is a
 sentiment that suggests that every interaction with a citizen may be 
the officer's last. Nor does it help when political leaders lend support
 to this militaristic self-image, as New York City Mayor  Michael Bloomberg did in 2011 by declaring, "I have my own army in the NYPD—the seventh largest army in the world."
The motivation of the average American
 cop should not focus on just making it to the end of his shift. The 
LAPD may have given us the first SWAT team, but its motto is still 
exactly the right ideal for American police officers: To protect and 
serve.
SWAT teams have their place, of 
course, but they should be saved for those relatively rare situations 
when police-initiated violence is the only hope to prevent the loss of 
life. They certainly have no place as modern-day vice squads.
Many longtime and retired 
law-enforcement officers have told me of their worry that the trend 
toward militarization is too far gone. Those who think there is still a 
chance at reform tend to embrace the idea of community policing, an 
approach that depends more on civil society than on brute force. 
In this very different view of 
policing, cops walk beats, interact with citizens and consider 
themselves part of the neighborhoods they patrol—and therefore have a 
stake in those communities. It's all about a baton-twirling "Officer 
Friendly" rather than a Taser-toting RoboCop.

 The Consumer Products Safety Commission does not have a SWAT team. An 
earlier version of this article incorrectly said that it does.
