Fruit of the poison tree

The Pakistani newspaper, Dawn, in its report on the botched CIA strike against Ayman al-Zawahiri, says:

A senior security official said foreign militants had frequently been visiting Bajaur and even Abu Faraj al-Libbi, said to have been No. 3 in Al-Qaeda hierarchy, had told interrogators that he had lived in Bajaur.

Note: Abu Faraj al-Libbi is one of the seemingly endless supply of al Qaeda #3s, now one of the CIA detainees who is being held at an undisclosed location somewhere around the world. It seems that his conditions of detention lead him to tell interrogators what they want to hear.

UPDATE 9 SEPTEMBER: Abu Faraj al-Libbi is one of the 14 secret CIA detainees now moved to Gitmo. [He should not be confused with Ibn al-Sheikh al-Libi, whose whereabouts are unknown; see also here]. And the Washington Post reports that al-Libbi's interrogation was a key source for the bombing.
