When I was at university, one of my classmates was a cop. He was petrified because that day, due to schedule issues, he had all his cop stuff locked in the trunk of his personal car. At the time, having that sort of weaponry on campus was a big deal. He would have been better off comming to class in full uniform (the exception for cops would not apply if he wasnt on duty or at least in uniform.) He knew what might happen if someone discovered his handgun/taser/mace was on campus.

I remember back in elementary school the YW in my class brought a huge kitchen knife with him in his backpack. He showed it to me. Later that day, he slightly cut himself with it in the toilet over a broken heart or something like that. Next day he was back to school. We called him sleeping bag because he was wearing his pants so low

I myself have been suspended for having a "weapon". The weapon in question was a bent paper clip. No I'm not kidding.

You probably remember when the cops would get called if you were caught with a cell phone or a pager at school.
