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.

      But what will be the reaction of the "activists" when these cameras capture indisputable footage of, say, somebody like Michael Brown launching an unprovoked physical attack against a police officer?

      Will they actually admit that maybe the thug involved wasn't such a "good boy", and that maybe it's incorrect to claim "but he didn't do anything wrong"?

      Will they just repeatedly deny what the footage shows?

      Will they start demanding the removal of these cameras, after the cameras repeatedly capture footage of incidents in which the police acted perfectly reasonably, and some thug did not?

      The response to the convenience store footage in the Brown case may be a good preview of how they'd react. It clearly showed Brown acting very violently, and clearly up to no good. Yet instead of accepting what it so obviously showed, the "activists" came up with all sorts of excuses, denials, and even outright fabrications regarding it.

      They'd probably ask why he tried to apprehend someone twice his size without any backup. Then ask, why after he'd already shot the guy 4 times he had to put 2 more bullets in his head.

      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. Only in very rare situations would that "quickly" move promote safety. It's unsafe to anger another driver, both to you and the next cyclist they come upon. You're not doing it to promote safety, you're doing it to express dominance, like a gorilla beating its chest.

      Next time you try that, think about this - are you doing it to promote safety, or are you doing it to try to express dominance by proving that you can legally be a dick? Believe me, the other driver doesn't care how big your penis is, so be the better person and don't be a dick or a dumbass to cars when you're on your bike, you're making the rest of us look bad, and it hurts us when we actually want to promote safety or policy changes (who wants their tax dollars to pay for bike lanes for a bunch of assholes like you?)

    While most people on here are focusing on the police portion, the civilian portion is more damning. It shows the amount of crap police have to put up with by people who think they'll file a brutality report so they can not be held responsible for their actions.

    I don't have the link, but some on here will remember the video of the woman who was in the back of a police car yelling and screaming for the police to stop hitting her without realizing a camera was recording the whole thing. When she claimed police brutality, the video was shown and the charges were thrown out.

    While there is certainly some police abuse going on, there are much more claims by people of police abuse where none exists. Just like dashboard cameras, it works both ways so when people claim they weren't doing anything when they were shot, the camera will show them reaching for their gun (see the most recent shooting in Missouri though we don't have video of the incident).

    Cameras are only a partial solution. While they tend to keep **both** sides honest and calm, they don't really change the fact that if the cop is in danger he will react with deadly force out of fear. Another part of the solution is to not send cops out alone, always have them go out in pairs.

    If a cop is alone and fears a person may try to take his gun he will not let that person get close enough for a wrestling match. He will shoot.

    If a cop is not alone he is far more likely to use a less-than-lethal weapon such as a taser or baton since his partner will have a lethal weapon at the ready should the person get ahold of the cop's gun.

    Cops are paranoid about losing control of their gun, according to the FBI about 10% of those cops shot are shot with their own gun. Having a partner greatly helps reduce this fear.

    We have no evidence that Brown was trying to take Wilson's gun, only the word of a cop who's been caught lying before. Cops know that "he was going for my gun" are magic words to justify themselves when they commit murders.

    Sorry, coroners reports say there was gun powder residue on Brown's hand. You are severely misinformed.

    And of course it's irrevelvant whether Brown tried to get control of Wilson's gun earlier in the confrontation. Brown was not trying to do so when he was murdered, he was (according to the majority of witness testimony) attempting to surender.

    You have progressed from severely misinformed to absolutely clueless. Minutes earlier he went for the cops gun, that is highly relevant and it absolutely controls everything that followed. It escalates the situation to "high risk". As "high risk" he is more likely to be pursued than to be left to flee. As "high risk" the officer is consider by training and law to be in danger and justified in not allowing the suspect to get close to him.

    Regarding witnesses, many have proven to be lying. Seriously, we have one lady changing her story once the feds showed up and said she didn't really see it, she just repeated what her boyfriend told her had happened because she wanted her boyfriend's story to get out there.
