Did that really happen somewhere? Google isn't showing me anything.
A friend of mine in jr high used to be really big into guns. And he would bring in gun magazines to read during class downtime. Teachers used to give him hell about it and tell him he can not read that in the classrooms. Then it turned into, he isn't allowed to read them during lunch, to he isn't allowed to bring them into the school period.
Some teachers weren't bothered by it, and he would read them anyways in those classes until the administration found out that he was still bringing in gun related reading material. They were afraid that because he read so much into guns that he might start bringing guns in and shoot people. He then disappeared for a week and when he came back he never brought in another gun magazine. He said he didn't get suspended, but I'm pretty sure he did with all the crap the school had given him over his magazines.
He was one of my friends that I spoke with every day and I had a couple classes with him. Sometimes one of our teachers would even say they wanted to look into his backpack to make sure he wasn't bringing those magazines in. And this was in like......early mid 90s.
