I suspect my answer will be one of my usual non-answers. I apologize in advance.
Police are given a tremendous amount of power. Because of this, it makes sense that they should have far less rights (including privacy) and we should face greater punishment for wrongdoing than the general public. Police should have no expectation of privacy. I’d even be comfortable with extending this to non-work hours as well. And the most minor of infractions should result in immediate removal from the police force and disqualification from any police force. You may think this is crazy and will eliminate good people from wanting to be police. But I suspect it will do the opposite. We’ll get the very best people with altruistic intentions. And we will pay them for their service.
I’m a white male and was threatened by a cop in the past. They told me that they could “take care of me” in the back of their police car (as he got up 1 inch in front of my face). It was terrifying. It doesn’t take that much imagination to see what it must be like to not be pale-skinned suburban kid. Who wouldn’t run when they see the cops in that context?
