How can you expect any random civilian to be a hero. Okay, so some random civilians in Texas somewhere were heros. But you can't expect EVERYONE, loving SCHOOL TEACHERS included, to be like that. Texas lucked out. Not everyone can do that.
The answer to school shootings is not expecting all civilians to be loving action heroes with guns and knowledge on how to deal with violent crazy people.
The answer is more emergency exits. Every classroom should have a window with a lever that makes it pop out. Just like on the school bus. There should be fire exits all across the outside of the school, either metal scaffolding and staircases or inflatable slides, leading from every second or third story window to the ground level. It's escape routes from every single god-damn room. Not guns in the hands of teachers. Not more armed security. Not repealing the second amendment. Not taking guns away from everybody everywhere. Just more loving god-damn escape routes.
Emergency exits are non-controversial. More emergency exists are objectively safer than the system we have now. Giving guns to everybody is controversial and not "objectively safer." But exits everywhere is safer. It might not solve the whole problem, but it is safer. Guns in the hands of everyone might be safer or it might be more dangerous. But emergency exits in every classroom can either be safer or nothing. It CANNOT be more dangerous. Either it helps or it does nothing.
if four academy trained police officers hid how would a forgetin teacher react lol
