Just curious:

If someone comes at you threating to pull a hand gun and putting their hands into their pants acting like they are going to pull it, what if any legall means of defense do you have for protecting yourself. Odds are he doesn't have a gun, but you never know. Say you were to pounce on him and subdue him, call the police and have him arrested. If he did not have a gun could you be faced with any legal problems?
