If the guy had a gun and dropped it and put up his hands, you would still not want people to draw?
I am sorry but I disagree with this. Many a criminal has changed their minds both ways. There is no way if a guy had a gun and dropped it would I give him a chance to reconsider his actions and then we are both raising to the draw.
He can always pick the gun up. If I am in that situation he will have a gun on him until I get back-up. I would not try to restrain by myself. I cannot tell you what to do. Every event is different from the next.
