The attack speaks for itself. Regardless of anything that may have led to it, what the attacker did was wait until the opponent was in a position where he couldn't defend himself, grabbed him from behind by the neck and when he had the kid defenseless on the floor threw as many haymakers as he could before anyone could stop it. It was calculated to be as violent and impossible to defend as it possibly could be. Whoever taught this kid to fight, ingrained it in him to fight like a coward. He does it well.
Far worse, is the chicken hawk coach that defends this kids behavior and acts like this is a kid who ever belongs on a basketball court or in any organized sport again. Absolutely repulsive and disgusting. Hopefully this kid will do some jail time, for what would be a felony in this state as he assautled the kid when he couldn't defend himself. But the fact this violent piece of garbage has a coach like this guy, who is perfectly willing to put this future career criminal back on the court proves this situation is utterly hopeless.
As for the DA's office. Inexcusable. This kid should have been in detention the next day. Do your jobs, you miserable slackers. What does it take to get an assault charge there. Does he have to pour gasoline all over the victim and set him on fire? Seriously, what does it take to get you fools to do your jobs?
