We talk with the filmmaker behind a new documentary exploring former NFL star Pat Tillman's death in Afghanistan, and the military's attempt to use it to promote the war.
"The Tillman Story" also tells the story of Tillman's remarkable family, and their fight to unearth the truth. When Tillman died in Afghanistan in 2004, the military declared him a hero. But it later emerged that the military covered up his having been killed by friendly fire.
