The logic [of John Lott’s theory of Mutually Assured Massacre] goes something like this. If most people are unarmed, the guy who’s carrying has tremendous power and can kill more or less with impunity, at least in the immediate aftermath of a shooting. No one can shoot back. But if everyone is armed or any given person might be armed, you’re going to be a lot more cautious about going for your firearm and shooting someone. Because they might be armed too. They might shoot back. Or the person next to them might be armed. If everyone is armed, everyone will be on their best behavior. Because they’re all equal in terms of lethal violence. Shootings will go down, not up.
In the abstract, where no humans actually exist, there’s actually a compelling logic to this. If I know you’re armed, I’ll be on my best behavior. You will too because you know I’m armed. Of course, in practice, almost everything is wrong with this logic. It relies on an extremely crude version of economic rational action and an even cruder form of game theory. This is particularly the case when you realize that the fraught, angry situations where people impulsively kill other people are by definition not rational. This doesn’t even get into situations like school shootings where the assailant usually intends to die in the massacre. It also doesn’t get into accidents, misunderstandings. It’s completely nuts.
But this basic concept: more guns, paradoxically, means more safety informs almost every aspect of current pro-gun politics.
Josh Marshall on the “good guy” with a gun.
The point here is that the whole core argument of the pro-gun lobby in the US, i.e. that everyone carrying around guns makes society more “safe”, is traceable back to a couple of shitty books written by one asshole in the late 1990s.
