That is an astonishing omission, because race ought to be an inescapable part of the debate. Gun-related violence and murders are concentrated among blacks and Latinos in big cities. Murders with guns are the No. 1 cause of death for African-American men between the ages of 15 and 34. But talking about race in the context of guns would also mean taking on a subject that can't be addressed by passing a law: the family-breakdown issues that lead too many minority children to find social status and power in guns.
