I’m pretty sure that hanging the prospect of a school shooting over students every day with systems like this, only increases the chances of one of them deciding that doing one is a viable solution to their own problems.

There’s countries out there with not dissimilar rates of gun ownership where school shootings aren’t part of their culture.

If you installed a system to stop kids from shoving Pop Rocks up their ass while running down the hall screaming, it’d be maybe a week before they figured out ways to evade it.
