Uh, if I encounter a gang rape, I'm going in. I don't care if I'm outnumbered; there will be pain and fists and blood and at least *some* of them are going to be broken before me.
I cannot fire bullets into that, it's too easy to hit the innocent I'm trying to protect. I can take a sword into that. I can take a cudgel into that, too. If they pull out guns, well.. one gun against six is about as good as one sword against six guns. I sort of accept that risk going in.
I live in a place where this is common, but not mexican-border common. The threats are similar, but they are different: a cartel party is a well-armed, fairly well-trained, battle-hardened and murder-ready group, whereas your garden variety rapist or mugger is not. Garden variety mugger is going to think twice about being involved in a lethal situation where he may get executed (partially not applicable here: many of our high-crime folks are drug dealers and other such who are at risk of death by criminal activity more than by state execution, so state execution is the most minor risk and thus not a deterrent; but they are also not the ones likely to mug random people), mexican cartel drug mob folks have murdered and will murder again. Garden variety mugger you beat back with force; mexican drug cartel you go in with the full assumption that these people *will* murder you if they're not dead.
Where I am, I don't need extraneous weapons. Fists work just fine, and any level of pressure really carries weight. I've been threatened by gangs, had multiple people crowding around me shouting and demanding money, and just brushed them off and walked; they are not prepared to follow through, and any amount of force is going to quickly drive these people away. When we get into hardened criminals, serial rapists, and organized crime, that ceases to work; I can inflict crippling injury faster with a cudgel, and I can inflict death faster with a blade or superior, and when they come in groups i will need to do one or the other with rapidity.
So you can have your border state. I still think firearms are not a wholly appropriate self-defense weapon except in extreme cases (i.e. organized mob crime), and I think they carry a significant liability. I can see the comparative advantage when facing an intervention scenario with multiple adversaries, versus an ambush scenario where a firearm may quickly become a liability rather than an asset; depending on how you're going to handle an intervention scenario, either may be a valid choice to avoid bystander liability, but a cudgel quickly becomes less useful as you increase the need for quick lethality. Sword offers quick lethality in closed quarters, firearm offers quick lethality with range, cudgel is slow for cripple or kill.
I simply can't control a firearm like a blade. At the moment I carry none because nothing I can carry provides an advantage: I can handle any situation likely to arise here WITH MY FISTS. If I was out in gangland and dealing with organized murder gangs, I would go for no less than a sword; at that point I have to accept lethality in self defense, and I probably can't reasonably deal with those people with my fists--or even if I can, I'm going to have to kill them with my fists anyway, so screw it, you get to meet three feet of steel.
This has got to be one of the dumbest posts I've ever read here on slashdot.
