Give 'em time...it's inevitable!!!
My now deceased, one time policeman uncle once said to me, “There is one sound that all thugs, thieves and “no gooders” recognize and fear and that is when a policeman jumps out of his squad and racks a shell into the chamber of his shotgun. All you see is the north end of a horses ass heading south. There is only one sound like that and it works every time.”
