This is very interesting. His story has gotten more and more elaborate. From he thought he saw a barrel in the car, to they shouted threats from the car, to Davis getting out and shouting death threats, presumably with a weapon in his hand. All this from a kid without a history of violence and a good record at school. So angry he was, that he was ready to kill? And Dunn, who has expressed racist and murderous views, was just an innocent guy bothered by noise pollution. GMAB.
Also, multiple threats of death? All that threatening and Dunn didn't have any time to drive away?
MOO.
