Duty vs. Conscience at Gitmo

Learn how Lieutenant Colonel Stuart Couch, a government prosecutor set on convicting alleged 9/11 conspirator Mohamedou Ould Slahi, changed his mind after getting access to details of Slahi's treatment at the U.S. prison in Guantanamo Bay. Couch, who was friends with a co-pilot of one of the jets hijacked on September 11, 2001, says Slahi was tortured.

"I felt like what had been done to Slahi just reprehensible," Couch tells David Brancaccio. " For that reason alone, I refused to have any further participation in this case."

In this web-exclusive video, Couch shares what he saw and heard at Guantanamo, and talks about his controversial decision.
