James Mitchell - Former interrogator for the CIA

HARDtalk's Zeinab Badawi speaks to American psychologist James Mitchell. He helped draw up and carry out the CIA's enhanced interrogation programme after the September 11th attacks. He personally interrogated some of the top terrorist suspects using the programme's techniques, including waterboarding. His critics label him a torturer, though he says he has nothing to apologise for and that what he did was harsh, though legal and necessary.
