A law enforcement official said the gunman was dressed in fatigues and
carried at least five full 30-round magazines of ammunition. In his
bag he had a one-page, handwritten note that said he wanted to kill
TSA employees and "pigs."

The official, who was not authorized to discuss the investigation
publicly and spoke on condition of anonymity, said the note referred
to how the gunman believed his constitutional rights were being
violated by TSA searches and that he was a "****ed-off patriot" upset
at former Homeland Security Secretary Janet Napolitano.
