Schools bullies and hats

So last week, my oldest was a victim of bullying. Two kids approached him in the school yard and took his hat and took his jacket off of him. He was wearing the jacket and hat at the time. So Thomas played it like he just lost it and he would just check the lost and found and it was OK. He never mentioned to me that two kids took these things from him until the next day. I asked him the following morning if he was going to be able to hang on to his jacket. He said that he would be able to if nobody takes it from me. So I wonder where the hell are the teachers in all this crap? Why don't they educate the students as to what needs to be done when something like this happens? I am pretty pissed off with the whole thing. Just a big piss off to me.
