A man was at a local casino bar. He was having a drink when a conversation with another patron became hostile as the patron threatened him with the believable comment, "Im in the mafia". The man decided to leave. On his way out he stopped and talked to security whom had been called to the bar. The man had a drink in his hand. Security asked him to put it down saying it was a "weapon". He put it down, explained the situation and then proceeded to do what he had been, leave and was told to by security. He went to pick his glass back up when one of the persons not identified but was with the known security put their hands on the person. Then man removed his hand. He was then subdued by 4 others and arrested as a citizens arrest for simple battery. Is "self denfense" or " a right to stand grostand ones ground" a defense to this? At interview by arresting officers the man explained he was defending himself and was in great fear.
