Man, this sucks for this kid...but, what if 2 guys go and rob a gas station and 1 guy is only the driver, he never goes in. Then the robbery goes way wrong and the cashier pulls out a gun and they both shoot each other and die.
Wouldnt it be right that the driver was charged in the killing, because he was an active participant that was involved in something that was illegal and someone got killed. Even though it wasnt supposed to end up in a death and he never got out of the car...
