There were kids waiting for the school bus shot in a crossfire. That is why they were suspended. Shooting the students at a bus stop isn't OK; even by "accident" when they were aiming at a target.

I don't know if they deserved the boot for a year but I'll put the blame where it belongs. On the parents. The kid's mom was so happy to get them out of the house early so she could watch Dr Phil in peace that she's won the booby prize of the kid home for a year.
Airsoft, where nothing is hurt but feelings.
