Just in case I'm ever being grilled in a police station and the cops are being pricks I can stand up, knocking my chair over, point harshly at the ground and say, "I know my rights you son of a bitch!"

Then either they will back off and get me a cup of coffee or two of them will grab me and ram my head into a wall which will cause an anurism 4 days later as has been known to happen.

No, but seriously, what are the rules in that situation?
