Less than a month after the December 2012 Newtown massacre, the National Rifle Association's then-president, David Keene, warned that the new White House task force on gun violence would “do everything they can to strip Americans of their right to keep and bear arms, to essentially make the Second Amendment meaningless.” Three weeks ago, after a killer shot three people and wounded eight near Santa Barbara, California, conservative activist “Joe the Plumber” posted an open letter to the victims' families. “Your dead kids,” he wrote, “don't trump my Constitutional rights.”*
