and reports against officers dropped by 87%
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).
