The document discusses the shooting of Rep. Gabrielle Giffords and others in Tucson, Arizona in January 2011. It notes that during the previous healthcare debate, Giffords' office was vandalized and she was featured on a Sarah Palin web site in crosshairs over her district. The shooting killed 6 people, including a federal judge and 9-year-old girl. Some pointed to heated political rhetoric as a possible factor, while others said both sides received threats. Tea Party groups denied the shooter was associated with them.
