This story provides yet more evidence that people being treated harshly (but not tortured; let's be clear about that) may make stuff up that they think their interrogators want to hear.

An excerpt from the NYT story:

The Bush administration based a crucial prewar assertion about ties between Iraq and Al Qaeda on detailed statements made by a prisoner while in Egyptian custody who later said he had fabricated them to escape harsh treatment, according to current and former government officials.

The officials said the captive, Ibn al-Shaykh al-Libi, provided his most specific and elaborate accounts about ties between Iraq and Al Qaeda only after he was secretly handed over to Egypt by the United States in January 2002, in a process known as rendition.

The new disclosure provides the first public evidence that bad intelligence on Iraq may have resulted partly from the administration's heavy reliance on third countries to carry out interrogations of Qaeda members and others detained as part of American counterterrorism efforts. The Bush administration used Mr. Libi's accounts as the basis for its prewar claims, now discredited, that ties between Iraq and Al Qaeda included training in explosives and chemical weapons.

The fact that Mr. Libi recanted after the American invasion of Iraq and that intelligence based on his remarks was withdrawn by the C.I.A. in March 2004 has been public for more than a year. But American officials had not previously acknowledged either that Mr. Libi made the false statements in foreign custody or that Mr. Libi contended that his statements had been coerced.

A government official said that some intelligence provided by Mr. Libi about Al Qaeda had been accurate, and that Mr. Libi's claims that he had been treated harshly in Egyptian custody had not been corroborated.

A classified Defense Intelligence Agency report issued in February 2002 that expressed skepticism about Mr. Libi's credibility on questions related to Iraq and Al Qaeda was based in part on the knowledge that he was no longer in American custody when he made the detailed statements, and that he might have been subjected to harsh treatment, the officials said. They said the C.I.A.'s decision to withdraw the intelligence based on Mr. Libi's claims had been made because of his later assertions, beginning in January 2004, that he had fabricated them to obtain better treatment from his captors.
