Legal: you never shoot to kill. You shoot to stop the threat. The fact that that will probably result in death is an unfortunate side effect. And you'll be better off in court that way, both because it doesn't look as bloodthirsty and because there will be only one story told in court.

That’s what this guy was doing. He was shooting to injure by his explanation of where he shot the guy and where he didn’t shoot him.
You do not do that. Even if you do, you don’t SAY that.
