For what, doing the right thing? Someone attacks you and you use force to repel them. What exactly is the issue here? The fact that the kid died was a freak accident that normally doesn't happen from a punch to the chin. So what now, is everyone supposed to succumb to bullies/attackers and not defend themselves....YOU attack someone, YOU SUFFER the consequences of that attack when they defend themselves. It's called self responsibility, I know that is a VERY hard concept for many to grasp.
