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.
Why did they bother calling the police on the kid? It's not like he punched someone in the face or something. I thought that there was something called "statute of limitations".
The only people with any common sense in this story were the fellow students who didn't make a big deal out of it.
