Wait, I thought this was a "mental health" issue, or a "moral" issue. Now it's a gun issue?
If you're ignorant enough to think that arming teachers is a solution, sit down and let the grown ups talk. You're probably a person who denigrates public education and supports all the massive cuts to it over that last two decades. (I'm looking at you, Texas and Oklahoma).
If it really is about mental health (we know that's just an excuse, by the way), then properly fund more counselors so they can be able to physically deal with kids while they deal with testing and scheduling and mounds of unnecessary paperwork.
We can't even get enough school supplies without buying them out of our own pocket, now you want to buy a bunch of guns (I hope you're also not stupid enough to think we should be forced to buy them ourselves), pay for a bunch of training, pay for a bunch of psych evals, pay for a bunch of maintenance and storage and management...and all the subsequent follow-up for these things.
Keep your guns. Most gun owners are responsible. Even the Rambo wannabes are mostly responsible. Keep your completely unnecessary arsenal. It's quite clear you love it more than you care about a few children who give their lives for your "freedom." Most gun owners support reasonable, common sense control. Most people generally feel the same. But, if you're irresponsible (how many toddlers shoot others?), have a history of violence, have a history of violent mental illness, or are otherwise cognitively impaired, you probably shouldn't have access to weapons designed to kill. Those are just a few example. You whined and cried that Obama was comin' tuh gi ur guns and nothing happened. Buck up, little camper, and let reasonable people try to alleviate this madness.
