Get home from a 15 hour shift, your noisy upstairs neighbor is stomping around like a water buffalo, since you stopped by the bar before you got home you are feeling your girl power, so you go upstairs to tell him to shut up with your piece on you. He gets belligerent, tells you "what are you gonna do, arrest me". I'm a damn cop, i'll shoot you. Ok shoot me then. Pop pop. End of story.
