There’s also the inherent problem of solving the problems of guns in schools by intentionally putting more guns in the schools. Basically the same thing as with homes: we know that having a gun in your home makes your family less safe, is that also true for schools?
look all I know is
A: nut comes into school, no one there has a gun: nut kills a lot of kids and teachers
B: nut comes into school with armed guards: nut tries to kill a lot kids and teachers and gets killed in the process. less kids and teachers are dead than would have been.
Also most of people who have guns in their homes aren’t trained police officers.
