He might have been aiming low, but hes an idiot for taking even one shot much less the last couple shots because thats way too far away to be shooting ur not gonna hit a tire from the backside esp from that far away that was just reckless...
And the mom is a dumb bitch, but shes just that, a dumb bitch. The cops however, signed up for shit like this and should be able to deal with it the right way. I dont think they teach "aim at car occupied by children from 1-50 yards away and fire, try to aim for tires though" at the academy.
