Seven people died. Himself, three roommates (where a gun wouldn’t likely have helped, most people aren’t packing around the house and on guard against a roommate whom they trust), and three passers-by on the street. Sounds like he was taken down pretty quickly. Unless, literally EVERYONE was carrying a gun, not sure if he could have been stopped any more quickly.
How would you make sure that everyone would carry? I for one wouldn’t be interested in carrying a heavy metal object everywhere I go. Would it be mandatory to be armed outside the house? If something like that ever happens, I think I’m dusting off my passport and moving abroad 🙂
Especially because a lot of people in modern society have anger/frustration issues. Requiring them to carry an easy, impersonal way to hurt another person is a recipe for busy emergency rooms.
