Another Mass Shooting: Guns in America

At least 12 moviegoers are dead and 58 wounded after a gunman in a gas mask shot up the Batman premier at a movie theater in Aurora, Colorado. The suspect, James Holmes, is 24 years old, said to have been a graduate student in neurosciences, and he left sophisticated booby traps in his apartment. We hear witnesses describe the scene, which has already set off debate about America's epidemic of gun violence. (We hear the voices of Shayla Roader and Jennifer Seeger on CBS News and Trey Fremon and Deshantay Harris recorded by NBC.)
