The supreme irony here is that, even if we take him at his word that he thought it was self defense...the guy he shot didn't have a deadly weapon...I assume we would have heard about it if he had. So he did basically the exact same thing that keeps occurring in these police shootings, but probably with less cause...and that he was out protesting against. He (again, or at least his claim) believed a life was in danger, and he fired his weapon to put down the threat. "Abolish the police, guys!"
