I'm unclear on which cases we're discussing. I see clear self-defense in the case of the guy he shot in the arm who had his gun raised. On the other cases, he killed one guy who grabbed his gun and one where the guy hit him over the head with a skateboard. On these, I'd bet on manslaughter of some degree, not being familiar with WI law. I do know that there have many cases which landed there when one person had a firearm and one had a knife. There is such a thing as disproportionate force and that's definitely there when one person is armed with a skateboard. I actually think the self-defense is stronger with the guy trying to take away his gun. After all, he could have taken away the gun and used it on the kid. In the end, I bet against murder and for one case of manslaughter, if not two...
