The problem is that the last paragraph just isn't true. We had guy working in a pharmacy here in OKC. Two young armed black men tried to rob them. He fired with his pistol hitting one and downing him. He chased the other out the door, but couldn't catch him. Security camera shows when he came back he fired more rounds into the guy while he was laying face down on the ground. Then when the gun was empty picked up a second gun and fired more shots into him. The guy is in prison for murder. His appeal lost. And the governor will not pardon him.
Those are the facts.... regardless of what the author of the article says about it not mattering how many rounds were shot.
