Great idea. The school can set up a firing range with tiny silhouettes in the gym for teachers to practice putting down a little child. We'll just add "marksman" on top of the other responsibilities they're already underpaid for.
Rifles with live ammunition? Yeah that does seem misguided in retrospect. Not as misguided as handguns in the classrooms IMO, but yeah, definitely not going to fly in these troubled times.
Honestly it was fine, that was before the shootings started. But once they did start they passed a federal law prohibiting guns on school campus and effectively ended the teams, which many did before anyway because "what if.." not that they were a problem.
