School wants to suspend my brother?

I'm so sorry that's really horrible but I think this is something your parents should deal with. They should go inside the school with your brother and speak with he principal. What your brother did to defend him wasn't the RIGHT thing to do but what these bullies were doing is absolutely HORRIBLE. So your parents need to speak with the principal and make your brother confess to what happened. when his glasses broke and such. But I'm so sorry about what has happened to you. Good Luck!
