Rapist at my school!

A girl that attends my art school went to the head of the school in deep concern last week. One of the guys in her class was saying weird things to her and stalking her. My school didn't do anything, they wouldn't even listen to her. They even turned it back on her saying she was being silly and blaming her for this stuff. She then went to the police and they found out that this guy was a sex offender who had previously stalked and raped three other girls. The police came and arrested this guy last week. My school is keeping this whole ordeal under raps, they aren't telling anyone. Everyone is extremely angry as ever at the school for not doing anything about this. After this girl came to them needing help and extremely concerned about this guy they did nothing. This guy isn't aloud to come anywhere near our campus or anywhere near the Woodfeild mall area now.
People are urging this girl to sue the school. Everyone is saying the school should pay for her tuition for this quarter because of this incident. People should be aware of this incident as well so they can be careful of this guy. There should be posters or pictures around letting people know about this so they can be careful.
However, the school is just keeping quiet. They don't want this incident to get out, they are doing nothing. The only reason I heard about this was because my teacher told our class. He said he was very angry at the school over this incident and that everyone attending this school deserves to know what happend.
