A suburban Washington, D.C., gun store owner who said he would sell the nation's first smart gun — even after a California gun store removed the weapon from its shelves to placate angry gun-rights activists — backed down last night after enduring a day of protests and death threats, the Washington Post reports. Andy Raymond, co-owner of Engage Armament, a store known for its custom assault rifles, had said that offering the Armatix iP1 handgun was a “really tough decision” after what happened to the Oak Tree Gun Club near Los Angeles. Oak Tree was lambasted by gun owners and National Rifle Association members who fear the new technology will be mandated and will encroach on Second Amendment rights.
