My question is on the legal end what happens if I'm on the crapper and the cops show up- no suspicious activity just me by myself- and they knock and I finish up and flush then they burst in on the assumption I'm "destroying evidence" because they heard a toilet flush? Or even worse if I don't hear them identify themselves as the police and I come around the corner gun in hand because I heard the door get kicked in? There has to be some sort of legal protection right? And I can send the bill for the broken door and frame to the local department right?
