For 14 years, John Kiriakou worked as an analyst and case officer for the CIA, leading the team that captured senior al-Qaeda member Abu Zubaydah in Pakistan in 2002. Then, in a television interview in 2007, three years after he had resigned from the US intelligence agency, he became the first current or former member of it to publicly acknowledge that the CIA used torture, and that its use was official policy under the administration of President George W Bush.
