This weekend's shootings in Tucson, Arizona left six dead and 14 injured. Democratic Congresswoman Gabrielle Giffords ? whom authorities say was the target of the attack ? remains in critical condition, while a Congressional aide, a federal judge and a 9-year-old girl are among the dead. The violence was the worst the state has seen in sometime, and in its wake, members of Congress beefed up security detail, while some worried if more attacks were coming. Since then, 22-year-old Jared Lee Loughner has been charged with attempted assassination. The event appears to be an isolated act of violence, but many are wondering: how did this tragic shooting occur?
