I had mixed feelings about this too until I read some of the comments under this article. There are posts from parents of children who attend school with these boys who, apparently, have been victims of their bullying and are disgusted by their "sweet angel" act. According to some posts (which may or may not be true) they even have juvenile records, previous suspensions, and many complaints in their pasts.
The school obviously cannot release this information, but you have to wonder why a principal would bring this kind of headache on himself without a good reason.
