It would depend on the size of the school, as in number of teachers and actual physical area, in my opinion. Also, cooperation and communication with law enforcement who would be clearing the building would be a necessity- the potential for friendly fire incidents is enormous. Some procedures about firearms use would be critical to avoidance of those. Also, there would have to be a great deal of discussion about which arms to use- FMJ rifle rounds would be a poor choice as most schools are built of concrete blocks and the range in most cases relatively short. Simply saying “Arm the teachers” is one thing, and doing it is a bit more involved. It is still the most logical and fiscally responsible step, though.
Sure. There can be nuts and bolts involved in setting up program up. Allowing and encouraging some teachers and staff to have firearms at the school would be an improvement on what we do now. Setting up a an actual plan would be a further improvement from that.
As for local law enforcement clearing the building, some consideration certainly needs to be taken – however by the time the police show up, it’s pretty likely that the situation would either be in stalemate or resolved.
And another comment: I agree that some situational training, especially including local law enforcement, probably should be a prerequisite; maybe some reasonable periodic subsidized range qualification. That is, however, a pretty low hurdle in implementing such a thing. Maybe include reading “in the gravest extreme”. It’s not rocket science.
