The growth in the number of civilians owning military-style guns can be traced back to a deal made in the mid-1980s between Rene Carlos Vos, a gun dealer, and Wayne LaPierre, chief lobbyist for the National Rifle Association. They formed a company called Blue Sky to import from South Korea M-1 rifles that had been used in the Korean War. The legislation that made the project possible was an amendment to a Senate bill offered by Bob Dole, Republican senator from Kansas, which for the first time allowed the importation of U.S. military weapons as long as they were “curios and relics.” LaPierre soon pulled out of Blue Sky when it faced criminal charges, and Vos was killed in a plane crash in 1987, but the company opened a floodgate of guns. By 2012, one million of what gun advocates call “modern sporting rifles” were flooding the U.S. market each year, from both foreign and domestic sources (Washington Post, May 3).
