This is a good point -- between a camera in every public place and a camera on every cop, the latter is far the better option, and can be empowering to the public interacting with the police. Just about everything it records is in the context of "member of the public knowingly interacting with a police officer", not "member of the public going about their everyday life" (which is much more ripe for abuse, and rather less likely to benefit the public in any way).
