Devyn Hembry leans on his Bushmaster rifle as he waits to get in line to enter a Washington state House panel hearing Tuesday, Jan. 28, 2014, in Olympia, Wash. Former Arizona Congresswoman Gabrielle Giffords, who survived a 2011 shooting, testified before the panel considering an initiative to expand firearm background checks in the state, telling lawmakers that "the nation is counting on you." With her husband, retired NASA space shuttle commander Mark Kelly sitting next to her, Giffords spoke slowly and briefly to the panel that was taking public testimony on Initiative 594.
