Not surprised in the least. This is what happens when you have a "zero tolerance" policy that goes with a "zero common sense" policy in public schools.
I used to be a school resource officer. I had school admin approach me about a student (elementary school) who they thought had terrorist magazines in their possession and called the child abuse hotline. Only to find out the child had a video magazine called "game informant" (nintendo video games magazine, etc) that had an ad for a military game. That's just one example of the stupidity.
