Quote from nutmeg:
I disagree with arming school staff. Sure you could teach the use of a firearm to staff, how are you going to hire staff who would kill a student? It's a conflict and a liability.
Imagine a student sitting across from a principle being disciplined and that principle is wearing a sidearm. Very threatening probably to a parent also.
I think a law enforcement officer would be the best bet.
We could limit access to the interior of the school but school shooters could wait till everyone exits.
We used to have institutions for the mentally ill. These were replaced with psych meds and the patients shuffled off to no mans land, ie shelters, group homes, the streets and prisons.
This is the trade off to save money and preserve rights. Death and destruction.
