Thanks, Jim. The comment didn't jar me for two reasons. One is that the main author of the book is a lawyer, and lawyers tend to be pickier than others about getting the facts right.

Another reason is that I've reviewed a lot of books on gun violence or control, pro or con. And an argument I've often heard made by the gun control side is that the framers of the 2d Amendment were thinking specifically of militias (and their right to defend the citizenry), not the right of everyone to carry a gun, anywhere. So a discussion of militias may have been "in the air" long before they became more of a thing in the 1980s and 1990s. I'm not a lawyer (or a 2d Amendment expert), but that's how it looks to me as a journalist.
