This is a rather lengthy review of the concept of applying insurance as a de facto regulatory tool for restricting gun ownership. Megan McArdle comes to the conclusion that it’s effectively useless, and so is a blatant admission that the move is an attempt at punishing lawful gun owners to the point that they voluntarily slow or stop gun purchases.
Summary: “The problem is, it’s not clear to me that any law which could actually be enacted would even a partial solution to gun crime. The people who will buy insurance will, by and large, be the people who have assets and social respect to lose by breaking the law . . . which is precisely why they’re quite unlikely to commit a gun crime. The people who are most likely to use the guns to a bad end will simply do without.”
