Stephen Sackur talks to John Kiriakou, the former CIA agent who played a key role in anti-terror operations after 9/11 and later went public with the truth about water-boarding. He was imprisoned for leaking the names of two CIA agents and is currently on federal probation. He says he is a truth teller scapegoated by the US Government - but he betrayed a trust - should that carry a heavy price?(Photo: John Kiriakou is honored with the First Amendment Award.
