Treat a cop just like you treat a gun when you don’t know whether it’s loaded or not. Assume that it is loaded and that it could cause someone’s death at any time. Remember that a cop, unlike most firearms, has no safety mechanism or standard method for “clearing” them. Never point a cop at anyone whose blood you could not accept having on your hands.
This! If you call the cops on someone you’re basically saying they deserve to die. Also, don’t leave people alone with a cop.
