Understand this: In the eyes of the Law, the gun is Lethal Force. Not ‘Stopping Force’–Lethal Force. Shoot someone, and it doesn’t matter to the Law that you just wanted to stop them; you have still employed Lethal Force. Deliberately shoot to wound, it won’t matter; you have still employed Lethal Force. (Shooting to wound isn’t guaranteed to just wound, either; people regularly die after being wounded in the arms or legs.)

Always worth repeating ...
