Actually, it's heartening to see the school take the logical and correct steps in canceling the season and canning the entire staff. Anything short of that would have been flat out wrong.
And spare me the 'poor kids' nonsense that always accompanies these stories and is always used by those who want to limit culpability in these cases. Those kids can all learn a valuable lesson about both the consequences of so blatantly breaking the rules, and, what happens when you are part of something you knew was wrong.
