When Robin Williams chose to exit this world via a belt rather than a gun, we were spared the usual spate of editorials on how the ready availability of guns provokes people to take their own lives, blah, blah, blah. Mr. Williams, however, lived in San Francisco where it’s more or less impossible to buy a gun unless you are Senator Diane Feinstein, whose life is so much more important than those of the rest of us.

The last I checked, belts are even more common than firearms, and you can buy them in San Francisco with no paperwork, but I have yet to read a single editorial denouncing their easy availability. If you can see no way forward and just want to end things, you are going to do it with whatever is at hand. Robin Williams was a hugely talented guy and, from all accounts, an admirable human being. May he find the peace in the next world that he never found in this one.

Future of the Gun is about firearms technology, the politics of firearms, and where guns and gun rights are headed in the future. It’s a strange, eminently readable book by Frank Miniter, whom I have known for years, and shot against.

Frank, unlike 90 percent of people who write books with titles like this, actually knows whereof he speaks. He does not confuse clip with magazine or bullet with cartridge, which I found unsettling at first, but quickly got used to. Nor does he drone on about the real meaning of Article Two of the Bill of Rights. He is a lively, entertaining writer, and his book is considerably more optimistic than I thought before I picked it up.

It’s 272 pages, $27.99, and is printed by Regnery Publishing,

I’m liberally quoted in it, which removes any pretense at serious scholarship, but then nothing’s perfect, is it?
