The more the police fail to defuse confrontations but instead help create them — be it with their equipment, tactics or demeanor — the more ties with community members are burned, he said. The effect is a loss of civility, and an erosion of constitutional rights, rather than a building of good will.
“What is most worrisome to us is that the line that has traditionally separated the military from civilian policing is fading away,” Mr. Lynch said. “We see it as one of the most disturbing trends in the criminal justice area — the militarization of police tactics.”
Police officials insist they are not becoming more militarized — in their thinking or actions — but merely improving themselves professionally against evolving threats. This is the way to protect citizens and send officers home alive at the end of shifts in an increasingly dangerous world, they say. Of course, in the event of a terrorist attack, they have to fill the breach until federal or National Guard troops can rush in.
“If we had to take on a terrorist group, we could do that,” said William Lansdowne, the police chief in San Diego and a member of the board of the Major Cities Chiefs Association. Though his force used federal grants to buy one of those fancy armored vehicles — complete with automatic-gun portals — he said the apparatus was more useful for traditional crime-busting than counter-terrorism.
“We are seeing suspects better armed than ever before,” Chief Lansdowne said.
Now the Occupy movement and highly publicized official responses to it are forcing the public to confront what its police forces have become. But analysts say that even here the picture of policing is mixed. While scenes from Oakland were ugly, the police in Los Angeles and Philadelphia last week evacuated Occupy encampments relatively peacefully; Los Angeles officers used a cherry picker to pluck protesters from trees.
Police officers are not at war, said Chuck Wexler, the executive director of the Police Executive Research Forum, and cannot imagine themselves as occupying armies. Rather, they must approach any continuing Occupy protests, now or in the spring, with a respect for the First Amendment and a realization that protesters are not enemies but people the police need to engage with up the road.
“You can have all the sophisticated equipment in the world, but it does not replace common sense and discretion and finding ways to defuse situations,” Mr. Wexler said. “You can’t be talking about community policing one day and the next day have an action that is so uncharacteristic to the values of your department.”
