Maybe the problem isn't so much schools as it is kids exposing themselves for their yearbook photos?
In Mesa, some high school kid who was part of a sports team exposed his junk for a yearbook picture. The people working on the yearbook didn't notice the prank until several days later. So, they called the police and the kid got 69 counts of indecent exposure.
I mean, obviously they punishment went way too far, but if you're going to pull your dick out during your yearbook photo, maybe it's a tiny bit your fault when you get in trouble for it?
Yeah, and it typically last longer than a couple of days, so I don't know what you're talking about.
