Mark A R Kleiman says a number of sane things, but also this:
Requiring everyone who wants to have a gun to apply for a discretionary permit . . . serves no good purpose that I can see. The same is true of making a national registry of firearms and their owners. . . .
If and when it becomes technically feasible, we also need a database of ballistic signatures so that a bullet or shell casing found at a crime scene can be linked to the gun that fired it, and that gun in turn to its last lawful purchaser.
I deleted three paragraphs between, during which perhaps he changed his mind.
Kleiman also mentions Social Darwinism and Herbert Spencer together, vaguely enough that I can’t tell whether or not he means to repeat the slander refuted by Roderick Long.
