I don't think it's an invasion of privacy at all. Wether you are or aren't doing something wrong, I'd rather a camera catch it and prove I'm doing something wrong than the court go on the word of a police officer. I do believe police officers should be forced to wear cameras AT ALL TIMES, because although I'm not one of those people who believe all police are corrupt and if you need to argue with one every time you encounter one of them, I've had my fair share of bullshit run ins with police. I do believe had the officers been wearing body cameras, my situation would have been handled much differently, and most situations would be handled different as well. Body cameras HELP citizens in my opinion
