Thank goodness these idiots don't believe in target practice. No injuries, luckily. Hell, it looked like, from point blank range, they were BARELY able to hit the damn BUS!!!
Actually, they looked more to me like they were gangsta wannabees - lots of attitude, lots of bravado, but when it came time to actually, ya know, fire the weapon, they had to work themselves up to the act. Notice they approached the door, backed off, danced a bit, came back, backed off again, etc. The article and cast weren't clear, but it appears a single shot was fired?
