re: Should cops wear camera's at all times while on duty?

Just saw this in the Tribune here last week; they're going to be mandatory for Columbia police officers soon. Seems like a good idea if you can remember to click record (there is a 30-second buffer but you do still have to click something to record). I think it's got to be good for everyone involved; should clean up some of the riff raff on the police force while also cleaning up some of the garbage that gets blamed on the cops.
