How Did This Happen?

Indianapolis is in a uproar over a story that two 6th graders had sex (supposedly intercourse, not the catch-all "sex acts") in a classroom while a teacher was present.
It was some kind of shop class that was shaped like an "L" and one student acted as the lookout/created a diversion while as many as 10 kids watched one 11 or 12 year old kid nail another.
The bigger problem is that the school felt no need to report the incident. It didn't come out til four months later.
Their defense? It only lasted 30 seconds?
How long did they expect him to be able to last?

The 12 year old boy who still lives inside me wants to say "how come I couldn't bang someone in wood shop in I.S. 72."
But the nearly 30 year old man who is about to have a child thinks "what the fuck is wrong with kids these days?"
