It's like if I catch a cockaroach I don't kill it, I maim it - I get a tweezer and pull off a leg and an antenna the poor bastard goes hobbling back to his buddies and says "Stay the he'll away from this place the owner is out of his mind, look at me." never have a problem. Guaranteed this guy will never jerk with your place again AND he'll tell his buddies, if he ever finds his way back, it's like psychological warfare.
