I have officiated high school basketball and college baseball for 38 years. It was a tough juggling act between working my regular job and officiating, but I am glad to have done it and still do. Thankfully, I have never been involved or known anyone that has been involved is any such incidents. There are laws in this state to help protect game officials. If a kid, parent, game administrator or anyone assaults an official, and this case is about assault, that person will face up to a $10,000.00 fine and and a two year prison sentence. My guess is that after reading outcomes of what goes on after these situations are disciplined is that if the official was not in any way seriously injured the kid(s) will be given probation and also will have to do some community work, plus pay a small fine. The kids, their parents, the schools involved in the game and the league the school plays in will be sued and this will probably be an easy win for the lawyer because of it being recorded. I saw the referee's neck snap pretty good, so I would imagine he has some whiplash or other neck ailment.
You can also find other assaults on YouTube between student athletes and game officials and student athletes against other student athletes.
