You don't own guns, so you don't have any understanding of how proper concealment/retention holsters work. The reality of the situation is that you cant steal something if you cant see it and you don't know that it is there.
I deliver to several elementary and middle schools. Mounted on the wall of each office is a heart defibrillator, a fire extinguisher, some HazMat breathing apparatus, and an extensive first aid kit for use by trained responders. Why cant there also be a 12 gauge shotgun mounted on that wall, concealed in a lock box, with access allowed only for teachers and administrators who have been trained in its use?
Standard protocol for dealing with a school shooting is to call 911 and wait for armed police to respond. All I am suggesting is that we cut the response time by having an armed responder in the office or classroom instead of 5-10 minutes away in a patrol car. Contrary to popular belief, the issuance of a police badge does not automatically confer upon its wearer some sort of superior ability with firearms. My gun club counts among its members several local teachers who carry concealed while working, and I have seen firsthand how good of a shot they are. God help the scumbag who tries to shoot up their classroom!
