At the Huffington Post, Radley Balko reports on a new ACLU campaign:
The militarization of America’s police forces has been going on for about a generation now. Former Los Angeles Police Chief Daryl Gates first conceived the idea of the SWAT team in the late 1960s, in response to the Watts riots and a few mass shooting incidents for which he thought the police were unprepared. Gates wanted an elite team of specialized cops similar to groups like the Army Rangers or Navy SEALs that could respond to riots, barricades, shootouts, or hostage-takings with more skill and precision than everyday patrol officers.
The concept caught on, particularly after a couple of high-profile, televised confrontations between Gates’ SWAT team and a Black Panther holdout in 1969, and then with the Symbionese Liberation Army in 1973. Given the rioting, protests, and general social unrest of the time, Gates’ idea quickly grew popular in law enforcement circles, particularly in cities worried about rioting and domestic terrorism.

Kraska estimates that total number of SWAT raids in America jumped from just a few hundred per year in the 1970s, to a few thousand by the early 1980s, to around 50,000 by the mid-2000s.
The vast majority of those raids are to serve warrants on people suspected of nonviolent drug crimes. Police forces were no longer reserving SWAT teams and paramilitary tactics for events that presented an immediate threat to the public. They were now using them mostly as an investigative tool in drug cases, creating violent confrontations with people suspected of nonviolent, consensual crimes.
