TheFragileI've seen some people throw around the idea of having chest cameras on officers, which apparently worked out pretty well in certain cities that have tried.
Mounted video cameras do deter unjust police violence, but that's a given. If I had a camera watching me here at work, I'd sure as hell do a lot more work.
Even this would be a huge step in stopping misinformation and hearsay w/r/t police encounters that turn violent. It's surveillance, sure, but surveillance isn't exactly going away, and I wouldn't mind having it working for me (the public).
Drug arrests (usually for marijuana) are also thrown around for being disproportionately and overwhelmingly affecting blacks above every other racial group. Profiling also isn't something you can catch on camera, unless the PO basically outs himself as doing so.
There are many ways to disenfranchise racial groups, however, and police brutality is the tip of the iceberg. Gerrymandering is basically a given in the U.S., every state in the union does it. Blatantly drawing district lines that harm the opposite party, and the regions that are split into the most districts are usually ones that have a high non-white population. To me, this is a blatant and absurd abuse of power, but it's been the status quo for this country for almost 200 years now.
Racism is ingrained into the very fiber of this country, and it almost seems like every government service, from law enforcement to voting and choosing a representative, is aligned to disenfranchise non-whites.
