Campus law enforcement does not endores it. No freaking problem. Then if I had a kid in school and they got shot by some wack ball. I would sue the living piss out of the place for not providing protection.
They don't want the kids to carry. No problem. Then put an armed guard in every damn classroom. Cause you know it is just a matter of time till some freaking idiot does a shooting again.
SUE. Or provide security for the kids.
