The [redacted by the CIA] picture [of Khallad, alias of Walid bin Attash] had been in the CIA’s possession when Steve Bongardt and the Cole team had been shown the [redacted] three pictures on June 11, 2011. If it has been shown to the Cole team, Steve and the other agents would have identified the man in the picture as Khallad. We knew exactly what Khallad looked like from the Cole investigation. And if we had learned that the CIA had had a picture of Khallad in June 2001, and had been monitoring him, we would have gone straight to headquarters saying that the CIA had lied about not knowing about Khallad, and we would have demanded that they hand over the information.
If that had happened, at a minimum, Khalid al-Mindhar would not have been allowed to just walk into the United States on July 4, 2001, and Nawaf al-Hazmi, [Mohammed] Atta’s deputy, would have been arrested. At a minimum.
