Some people have referred to a wild west shootout if armed guards are allowed in schools. If this the case, why are they not deadly shootouts in US banks every year. Or shootouts at airports. They have armed guards there.
Well, to think about it logically, bank robbers don't go to banks to shoot people, they go to rob them. If a bank robber does his job right, he makes off with the money without ever having to pull the trigger. If the guard does his, he prevents the robber from getting the money or getting away, hopefully without shots fired as well. Not a shot needs
to be fired for either side to be successful at their 'job' in either case.
By contrast, putting armed guards in schools is not meant to prevent people robbing them, but rather prevent people from killing the teachers, students, etc. In any of these events, no person goes into the school to not
fire upon people, and the result is often either the shooter killing themselves or being shot by police. A school shooting situation isn't likely to end up with the guard disarmed and no shots fired from then on, but rather the guard would be shot and then the shooter going on as if there wasn't a guard to begin with. The guard would also be much less likely to just put down his/her weapon in hopes of a non-violent end knowing the shooter's plan is to kill people, particularly children.
Continuing that, the amount of people who would have to be hired (likely with low pay compared to and armed bank guard since there's no money for education, let alone guards) probably wouldn't suggest a high quality of person prepared to cover a building with multiple entrances, plenty of spots in which to hide and a huge square footage. The possibility of the quality of shots fired likely decreases, and the possibility of unnecessary shootings increases due to quality of training, type of situations, people that are being protected, etc.
Consider it more of a situation like a convenience store robbery. A number of stores have weapons behind the counter, and even if they don't shootings still happen as the robbery becomes confused and the robber or worker becomes stressed.
