I'm not usually for mass surveillance, but I've seen reports of successfully altered behavior by cops who wear body cameras. Perhaps it would be a good idea to have all cops wear such cameras as a mandatory prop as long as they're on duty.
It's funny how accountability alters the behavior of certain people.
What's worse is that the cop probably would have gotten away with this if he was not filmed.
The most scary part is however how casual it all is. Like the citizen's life has no value.
