In any of the threads I've read on this, no one mentions the other kids who are standing around and egging the bullier on, while laughing at the situation. I believe they are guilty also, and should have been suspended. It was a gang bang. The tall kid with the back pack was probably the ring leader. I also believe that the camera person was documenting the bullying for the purpose of humiliating Casey further. They never in a million years expected to document Casey taking action. I am also hopeful that Casey would have done the same thing to the back pack dude had not the tall chick stepped in and got back pack dude to get lost.
Aggressor got less than he deserved.
Props to that chick for stepping in. That dude with the backpack would have gotten clocked if not for her.
