Bully's attacker in trouble

A high school student at Huntington Beach High School is in trouble after beating a blind student in the head.  Another student stepped in to stop the attack.  One punch put the bully on the ground.  Now the hero is being punished for also using violence.  It just doesn't seem like justice is being served.  It's true that violence is not the answer but to punish him for doing what's right doesn't seem to be the answer.  hero
