Is it normal to withhold someone's property until they pay you back?
My ex-housemate owes me heaps of money and he moved out. I caught him in the act (while he was unloading the first lot in his new house) and packed up his remaining stuff and stored it away in a secret place. I won't release it until he pays up. He even sent the cops around and I STILL wouldn't release his stuff. (The cops had no warrant so i told them to get off my property and they did. Ex-housemate left the stuff behind so there was nothing the cops could do as I haven't broken the law.)
