Is it normal to bar the police from your home if they don't have a warrant?
My housemate moved out owing me lots of money but made the mistake of leaving half his stuff behind. I packed it up and moved it off site and said, "Pay up and then I've give you your stuff." But ex-housemate sent the cops around instead. Of course, they could do nothing as it is not illegal to retain stuff in your house that someone's left behind. So I told the cops to go away and there was nothing they could do. They couldn't arrest me, nothing. I felt so empowered.
