As a substitute teacher, I've seen a lot of situations where certain students do not recognize a teacher's desk as sovereign. In other words, I've had to reprimand students as young as kindergarten who will go into a teacher's desk, that is, open closed drawers, to take out hidden objects they are denied. Stuff like Playdoh, slime, spinners. Juvenile breaking and entering goes to a whole new level if a teacher has, say, a Glock in the drawer, not a Fidget Spinner. (Obviously the teacher wouldn't have the weapon on top of the desk among textbooks, collected work, etc.)

I shudder when I think of past experiences with these kids if they had found a gun instead of slime in the drawer. I promise you these kids would have been delighted with the find, aimed at me (or other students or themselves).

With this "suggestion" of arming teachers, I can only imagine being a substitute for a teacher with a hidden weapon who forgot to take it with them and a student finding it before I do . . . . . .
