> For seven months, just over a thousand Washington, D.C., police officers were randomly assigned cameras — and another thousand were not. Researchers tracked use-of-force incidents, civilian complaints, charging decisions and other outcomes to see if the cameras changed behavior. But on every metric, the effects were too small to be statistically significant. Officers with cameras used force and faced civilian complaints at about the same rates as officers without cameras. ... > Another possibility is that officers without cameras were acting like officers with cameras, simply because they knew other officers had the devices. Or it also causes organisational changes. You can imagine the kind of things high-ranking officers will be telling their reports if they know things are going to be recorded. Is the problem a few bad apples? Or is the problem training and discipline? If it's the later, then cameras can probably do a lot more, by scaring the Inspectors into doing their jobs properly.
