Study: Police Body-Cams Reduce Unacceptable Use of Force

An anonymous reader writes: Incidents like the Michael Brown case have recently put police body-worn cameras into the public consciousness, but they're not a new idea to criminology experts. In fact, researchers at Cambridge began a study in 2012 using law enforcement in Rialto, California as a test bed. Their results are now in: "The experiment showed that evidence capture is just one output of body-worn video, and the technology is perhaps most effective at actually preventing escalation during police-public interactions: whether that's abusive behavior towards police or unnecessary use-of-force by police." The simple knowledge that both parties are being watched puts a damper on violence. "During the 12-month Rialto experiment, use-of-force by officers wearing cameras fell by 59% and reports against officers dropped by 87% against the previous year's figures." This was enough for the city of Rialto to decide it wants to move forward with body-worn cameras; hopefully the study will encourage other police departments as well.

      Why do you think that cops were more accountable 30 or 40 years ago?

      Before an answer, I will say that a large part of that trust came from being ignorant to the way the world actually works. I was young, delusional, and believed that authorities would never lie. Outside of Nixon and Kissinger of course. Hindsight is 20/20 as they say, and looking back I don't believe they were as accountable as I wanted to believe.. but there are several differences between today and then in attitude and training of law enforcement.

      Back then, police were not held in a higher regard than the public. Respected, sure.. but a cop's actions were measured by their risk to the public. For example, the commando style raids we see today are a very new phenomenon. 30-40 years ago this would not have happened unless someone's life was in eminent danger. Today we have commandos chucking grenades into houses to serve warrants. We have commando style raids for non-violent crimes like drug dealing. Cops shooting family pets because they claim "I was afraid of the dog". Those things simply did not happen back then. Police were expected to respect the public as much as the public respected them.

      There are many other differences in training and actions found to be acceptable then and now. A cop shooting someone today can simply use the excuse "I thought I was in danger", even when it's a kid playing army with his buddies. That would have had an officer suspended without pay 40 years ago, and back then there were many more kids out playing army/cops & robbers, etc.... Toy guns were much more common, hell we brought them to school to play at recess.

      Lastly hiring practices are much different then and now. Then, there was more worry about public perception of officers. Cops were expected to outsmart the bad guys, not kick their asses. Today agencies want the ass kickers, bad asses, and bullies. "Gangs" are not something new, so that excuse does not work as the justification.

      "Quickly?" In other words, you're riding along the right hand side of your lane, and as a car approaches intending to pass you, you quickly move into the middle or left of the lane to force them to quickly slow down to prevent passing. Doing anything "quickly" that obstructs others is a dick move and you know it. You're an asshole who makes the rest of us cyclists look bad.

So if you actually care about people getting shot you should care about violence against police.

      No, it goes both ways. Police who are overly aggressive and verbally abusive tend to provoke ordinary citizens with a sense of dignity and self respect. When citizens reply verbally in kind to unfair and abusive treatment from the police, the unfair, abusive police escalate and turn the situation violent where the situation should not be violent. This is one of the reasons police cameras work. The police tend to self-monitor and self-censor their overly agressive and abusive behaviors before a confrontation begins to escalate. So a cop is much less likely to start a traffic stop interaction with an angry comment like "What kind of fucking moron drives forty eight in a residential area?" if they know it is going to be on camera for their boss to see.

      Not all cops, of course. I have been pulled over by many polite and respectful police officers. And of course, police typically have to deal with drunken belligerents more than church choir members. But someone who is drunk should still be treated with respect, not verbally abused, even while they are being arrested and jailed.

    Except that the "choke hold" had nothing to do with Garner's death. His death was caused by lying on the ground with a man kneeling on his back. As clearly evidenced by the fact that he was still able to talk. If he was being choked, he wouldn't have been able to move air through his neck at all. Because he was being crushed instead, he could move air *out* but not in. He could speak but not breathe. Later, when he was moved into a position where he could have breathed, he had difficulty because he was asthmatic. Then he had a heart attack because his heart was working harder to move oxygen around his body. Then he died.

    When you talk about the "choke hold," you distract from the real issues. They should not have thrown an obese man onto a hard surface. Given that he was lying on a hard surface, they shouldn't have kneeled on his back. Those are areas where a policy change and training could help. Yet instead of concentrating on the tragedy, your narrative tries to assign blame. By doing so, it distracts from taking actions that could prevent similar tragedies in the future. Instead of looking for policy changes, you are focusing on blaming the officer. If you succeed, people will say that the choke hold was already banned and no policy changes would be made.

    Every time you say "choke hold," you open yourself to debunking. The proof that there was an illegal choke hold goes like this: the officer's arm was near Garner's neck; Garner said he couldn't breathe; therefore, the officer's arm was choking Garner; NY police ban a particular hold that can be described as a choke hold; therefore, the officer was engaged in an illegal choke hold; Garner died; therefore, his death was caused by an illegal choke hold. However, Garner saying that he couldn't breathe proves that he was *NOT* being choked at that time. Police claim that the officer's arm was not in a position to apply the particular hold that was banned.

    That's the problem with false narratives. They don't hold up under scrutiny.

    Of course, there's another problem now that will likely prevent policy changes. The deaths of the two officers leave the police much less likely to compromise on new training to prevent incidents like this in the future. They're dug in now and unlikely to engage rationally.
