The study, which just appeared in Volume 30, Number 2 of the Harvard Journal of Law & Public Policy (pp. 649-694), set out to answer the question in its title: “Would Banning Firearms Reduce Murder and Suicide? A Review of International and Some Domestic Evidence.” Contrary to conventional wisdom, and the sniffs of our more sophisticated and generally anti-gun counterparts across the pond, the answer is “no.” And not just no, as in there is no correlation between gun ownership and violent crime, but an emphatic no, showing a negative correlation: as gun ownership increases, murder and suicide decreases.

The findings of two criminologists – Prof. Don Kates and Prof. Gary Mauser – in their exhaustive study of American and European gun laws and violence rates, are telling:

Nations with stringent anti-gun laws generally have substantially higher murder rates than those that do not. The study found that the nine European nations with the lowest rates of gun ownership (5,000 or fewer guns per 100,000 population) have a combined murder rate three times higher than that of the nine nations with the highest rates of gun ownership (at least 15,000 guns per 100,000 population).
