The only reason I would ever point a gun at someone is if I were going to kill them. There is no shooting to wound. Unless you are sure that your life is in jeopardy, you shouldn't point a gun at someone.

Matter of fact if you have a ccw and you are carrying, it is illegal here to pull out your weapon in public for any reason other than to use it (exceptions, of course, include allowing a LEO to disarm you after stating that you are armed and stuff like that).
