After Tucson, a New Focus on Guns

By John R. Lott, Jr.

To the Editor:

Nicholas D. Kristof attacked my research in his Jan. 13 column. While conceding that “concealed weapons didn’t lead to the bloodbath that liberals had forecast,” Mr. Kristof asserted that “many studies have now debunked” my finding that more guns lead to less crime.

In fact, the overwhelming majority of studies support my results. Among peer-reviewed studies in academic journals by criminologists and economists, 18 studies examining national data find that right-to-carry laws reduce violent crime, 10 indicate no discernible effect and none find a bad effect from the law. Among non-refereed studies, three find drops in crime and two say either no effect or possibly small increases in crime.

Mr. Kristof cites a public health professor’s suggestions for one-gun-a-month sales limits, gun safes and further background checks, but I know of no academic criminologists or economists who have found that these laws reduce any type of violent crime. No gun ban has reduced murder rates. John R. Lott Jr.
