Mohsen Sazegara (محسن سازگارا), Ayatollah Khomenei's press attache, former head of Iran Radio and Revolutionary Guard founder, was interviewed on BBC Radio 4's Taking A Stand. He made the journey from revolutionary true believer and regime mouthpiece through to reformist newspaper publisher. In the interview though, he fudged a few of the hard questions: particularly those around why he did nothing when political opponents were being executed in prisons.
Interviews like this are supposed to be where people say how sorry they are, if they could go back they would change things, etc. Maybe it is better for people to show no remorse, to avoid giving a straight answer and to simply move on to the next question.
The interview was reminiscent of "Abu Jandal" in I Was Osama Bin Laden's Bodyguard. Jandal is quite clearly still in agreement with al-Qaeda/Bin Laden's critique of the West, goals and up to a certain point, attacks on military targets, methods.
