Pretty much, Korp.

Some teachers may be capable, and worthy of such a task. In my experience, though, teachers can be overtaken by individual students, despite age and sometimes size disparity. What happens in a scenario where a teacher loses their gun? If someone's already been denied a weapon, now you could be providing them with one, I guess. The idea feels good in some aspects, but I think it also has a lot of pitfalls.

I assume they would have to strap, because eventually, if kept in a safe somewhere, a teacher or student will get shot while punching in the code or whatever, and that won't be acceptable either.
