What would you do if you were told to do whatever was necessary to get a prisoner to talk? This is the situation that career CIA officer Glenn Carle found himself in when he was made the lead interrogator for a detainee who was said to be a member of Al Qaeda’s top echelon. Carle, the author of the recently published book, The Interrogator: An Education, tells Peter what it was like to be in this position. And, he describes how he got on the wrong side of CIA Headquarters (HQ) when he objected to the treatment of the detainee, who he came to believe was not who CIA HQ said he was. Listen in on a discussion that raises profound questions about American values and the struggle against terrorism.
