Not so crazy.. when I was 13 and somewhat of a troublemaker I had a cop shove his gun in my face and have no doubt he would have fired if anyone in the pickup I was in did not follow his exact orders. Myself, another 13 yr old, a 14 yr old two 15yr olds and a 16 yr old. None of us were armed, or made any aggressive act towards him. He caught us knocking down mailboxes, maybe he thought one of us would take a swing at him with a bat, but we had tossed the bats when we saw flashing lights and the guys that had them were in the bed of the truck... I was in the passenger seat already with my hands firmly placed on the dashboard. Yet I got the gun up the nose... don't ask me... either way though, I never knocked down another mailbox.
What they did was assault on a police officer. Child or not, assaulting a law enforcement officer will result in instant death.
