We have a pedophile as a teacher in our school.

I don't understand why our school principal (big boss) hasn't fired him yet. At his last school he was fired for saying things to boys like "youre a mommies boy, are you gonna go tell your mommy now" after he has yelled or disrespected students, and for going onto a girls profile picture and then inboxing her "just blew my load from looking at your profile picture... Thanks"
I even have the website that states he has done this disgusting stuff.
Ok so they thought it would be OK to give him another chance at a different school.
Over the past several months us girls and boys have reported him for doing really disgusting things, such as touching us repeatedly, and saying very rude and sexual comments "I'm going to bend you over (name) and Spank you if you don't stop being naughty", continuously swearing e.c.t.
He also looks like Trevor from GTA which is a bit creepy.
So on, we have another issue at our school with this boy, who sexually harasses girls, yet they haven't suspended him or expelled him. There was two recent incidents, that he should have been expelled straight away but they said "we will give him snother chance, we don't have hard core evidence".
1st recent incident he was caught having sex in the toilets with another girl.
2nd recent incident he slapped my two friends on the ass and flicked their boobs.
The principal did NOTHING about it, and said to my friends that they needed hard core evidence.
I'm done with my rant, thanks for listening.
