Details are hard to come by, other than what is on YouTube.  In this clip, that is apparently Assistant-Principal Mrs. Samp is in a scuffle with a student over his hat.  While I don't know the rules of the school, I'm assuming he had his hat taken away for a reason.  Watch it and see for yourself.  However, I do know that if one of my kids ever acted that way towards a teacher, there would be hell to pay when they got home!
