Can you prove in any form what so ever that these kids were threatening him? And before you start, yes he does have to show his life was in reasonable danger. Just like every other self defense claim in history. You have a group of unarmed teens that he approached. They did not assault him. Noone heard them threaten him. Noone saw a gun. There is no actual indication that any of that happened. The only thing that is known really is that he shot the truck up and then fled and hid from the police. A man who shoots in self defense does not do that. He calls the cops and reports the incident as the law requires.
