He didn't shoot them by accident, he shot them by negligence. There's a big difference. Legally, it's even worse than that. He was intending to shoot and kill the driver of the car, this intent is carried on to the inadvertent recipients of his gunfire, so in a just system he would be facing three counts of attempted murder. Self defence doesn't apply here, by the fact that he was a party of the protest that was impeding traffic, he (and his companions) created the conflict that he was supposedly defender against. There may well be other aspects of self defense law that he fails on too, but failure on any aspect is terminal to a self defense claim.

Yeah, that little commie faggot tried to MURDER the driver and passenger in the jeep (They were just trying to get to the airport and didn't know about the fake 'protest'). He ended up attempting to murder other commies.

These people are not smart.

Sammy Squishy Soy Young shot the rear of the jeep twice then nailed one protestor in the thigh, severing the femoral artery. He then proceeded to score a grazing head shot on another Summer Of Floyd fanboy. Ol' Sixgun Squirrely Curly was tried and subsequently convicted of 7 felonies. The Denver judge sentenced Sam-I-Am to.......wait for it .......... 120 whole days in the pokey (with 50 days time served) followed by 5 years probation.
