I would modify this a little. Rock is nowhere near as dense as lead, so I would use lead, formed into balls so they will fly straight. Also, it's sexist, racist, ageist, and otherwise exploitative to make a child's defense against violence depend on muscle mass. The schools should include a simple and reliable mechanism for accurately launching the lead balls at high speed.

My vote: "Glocks, not rocks." It's a shame leftists are . . .

Of course I want armed teachers. Frankly I think anyone with a CHP should be allowed to carry everywhere but through permanent metal detectors. And get rid of that stupid school gun zone law of 1990? which makes anyone who carries legally out of state a criminal at some point I their visit
HOWEVER if the lone murderer is looking for a body count a determined defense most likely will see him moving on and looking for a softer target. This assumes the schools run some sort of drills but I see that as unlikely. Might scare some snowflakes. U recall years ago the suggestion of canned food instead of rocks. At the end of the year have a food drive.
