None of that's necessary to stop an active shooter. 'yOu'rE jUst a lOoT DROp' is fallacious reasoning when we've plenty of examples where someone has taken out an aggressor with just a sidearm of your choice.

Never mind Rittenhouse fending off an entire mob with just a basic-bitch AR and a sling.

But, I suppose the argument works when you're operating in a bubble and know nothing about any of the above. Funny, that.
