Nick Leo visits a memorial for shooting victims on Tuesday, Jan 8, 2013, in Tucson, Ariz., outside the Safeway supermarket where a gunman opened fire on former Rep. Gabrielle Giffords as she met with constituents in 2011, killing six people and leaving 12 others injured. Giffords and her husband launched a political action committee aimed at curbing gun violence on Tuesday as her Arizona hometown paused to mark the second anniversary of the shooting rampage.
