And if you want to run it just as an experiment to gather data, your investment cost seems awfully high. Teachers need to be equipped and trained, not just in handling firearms but also in handling combat scenarios to avoid friendly fire incidents, improperly cleared rooms, etc. And this kind of training would of course need to be continuously refreshed to make sure your teachers are combat-ready at all times.
Considering how teachers already have their hands full and how schools are already struggling with funding, this seems like a steep entry cost for an experiment.
Basically, I can see how your solution could work, but its chance of success seems so slim I wouldn't even consider it a promising trial candidate.
Since I haven't heard of any solutions that seem very likely to work, I think it would be wisest to first invest in some research. We need more data.
Let the CDC study gun violence again, and try to look towards nations that are overall similar to America but don't suffer from America's unique gun violence problems. Isolate the relevant differences, copy what seems to work, and run some experiments in certain cities/states to see if it also works in America.
