RE: Principal, teacher suspended for letting sex offender into school...
There is a chance that since the offence occurred in '95 that he is "free" to be around minors again. I'm not sure the principal is at fault here. The teacher and her husband are if he hasn't gone past his "free" date.
I unfortunately know a guy like this, he couldn't come into a school for six years, but after that he was free to do what he pleased.
