Allow teachers to concealed carry guns to schools for self defence
But dont force any school teachers to carry. Nor mandate them to save others from a shooter. They should just be allowed to carry guns to schools everyday for their self defence.
When those teachers defend themselves using guns, they may indirectly save many others too. Also shooters will think twice before storming a school as there would be 10s of guns inside the school, with bullets coming from any direction. Gun free zones are the favorite places of mass shooters, and we should make schools are not the ones. Only teachers who have already worked for more than one year in a school can be allowed to carry the gun
