Guns aren't shields

[unblock]

3. guns are inherently offensive weapons, not defensive.

any defensive value comes from either
(a) stopping a threat by shooting them before they can shoot (more) people or
(b) stopping a threat by threatening to shoot them and they decide to not to shoot (more) people.

(b) doesn't work very well in mass shooting situations because in nearly all of these, the shooter has accepted that they probably will not come out of it alive anyway. they're not likely to stop just because they're threatened with a death they were planning on anyway.

(a) doesn't always work well because the shooter who planned the attack has a huge tactical advantage of having planned and prepared for it, whereas those shooting in defense are not prepared to die and are unsure how many shooters there are, what weapons they have, how much ammo, etc.
moreover, the shooter in at least some of these cases have *actual* defense in the form of bulletproof vests and such.


some of the actual building defenses i've seen in videos are cool -- for instance, in an emergency, walls can come down in a number of areas, making it hard for a shooter to advance from one area to the next.
