You are the manager of a bookstore. A customer becomes irritated at having to stand in line and begins to shout at the salesclerk for refusing to wait on him. You come out of your office and ask the customer to calm down. He shouts at you. You tell him to leave. He refuses. So you and the salesclerk pick him up and shove him bodily out the door. He calls the police to have you arrested for assault. Should the police arrest you? Assuming that they do, how would you defend yourself in court?
