This is why we keep arguing over the legality of the third shot.
DNS maintains the first two shots were legally excusable, but the third was not. Technically, DNS may be correct. Morally and ethically, though, that law would justify Dickens' line in Oliver Twist:
"If the law supposes that.... the law is a ass, a idiot. If that's the eye of the law, the law is a bachelor; and the worst I wish the law is that his eye may be opened by experience - by experience."
