Arizona Gunman Was 'on a Mission'

The "shady individual" showed up at a public gathering for Rep. Gabrielle Giffords asking to see the lawmaker. Told he would have to wait his turn, the man left but returned minutes later and gunfire erupted. The gunman targeted Giffords as she met with constituents outside a Tucson supermarket. Arizona's chief federal judge and five others were killed, and 13 people were wounded, including Gifford.
