Brilliant if you want to see the crime rate explode.
Who the hell is going to want to be a cop under those conditions, knowing every time you have to take down a suspect your actions are going be given an anal exam?
Who wants to be a cop today? Other than thugs and bullies?
I’d say those who WANT to help and do good would welcome the extra evidence to back up their claims. Unless you’re suggesting all cops do need to lie and don’t want to be called out for it via a body cam.
Today they have people telling stories and they are getting arrested for it (see Baltimore). If they had body cams then the evidence would clearly show they did nothing wrong (if they are telling the truth). If they are lying...well they should be in jail then.
