Why are the mentally ill still bearing arms?.

On Jan 8, 2011, a 22-year-old high-school dropout named Jared Lee Loughner allegedly opened fire at a "Congress On Your Corner" meeting outside a grocery store in Tucson, AZ, USA. Using a 9 mm Glock 19 semiautomatic pistol, Loughner shot US Congresswoman Gabrielle Giffords and then fired indiscriminately into the gathered crowd. Six people died and 19 were injured by the less-than-a-minute shooting spree, which ended when an injured bystander tackled Loughner as he attempted to reload.
