LAWRENCE A. WITTNER – The discussion of the Tucson tragedy should be familiar, as we witness similar massacres in U.S. schools, shopping centers, and other public places played out periodically. Each time, the NRA and other gun apologists tell us that the easy accessibility of firearms, including assault weapons, had nothing to do with it. Indeed, they argue that the key to our safety is to obtain more guns. But does the fact that nearly 100,000 Americans are shot with guns and nearly 10,000 Americans are killed with them each year really have no connection to the remarkable availability of guns in the United States?
