I thought the opposite. I was going to say, at least they made sure the intended target was there before opening fire. Many people have been killed in shootings and the intended person wasn't involved.
Detroit never surprises me.
Ok, but if they had any brains at all they would do a little recon and actually know what the kid looked like, his daily patterns, ect. Why the fuck would you attempt to kill someone at a bustop with shitloads of witnesses? Better off waiting for him to get off the bus later, and pop him once in the head. As an added bonus you wouldn't shoot any random innocent bystanders.
