My dad was an attorney. Just to say: we are white. And he said this to me: Police have in IQ of 80. If you are pulled over, place both hands at the top of your steering wheel with your fingers spread. Be polite. Move only when they tell you to.
Break any of these rules and they will kill you.
This is what he told his white son. He didn’t trust cops at all. This was in the late seventies.
