Analysts used subsource development and document exploitation to crosscheck detainee testimony, leverage detainees in debriefs, and to fill gaps in information. For example, analysts interviewing Huwaysh gained insights into his personality from subsources, while translated technical and procurement-related documentswere critical to verifying the accuracy of his testimony. Likewise, we confronted Vice President Taha Yasin Ramadan Al Jizrawi with a captured document indicating his major role in allocating oil contracts and he divulged details on corruption stemming from the UN's OFF program.Nonetheless, the interview process had several shortcomings. Detainees were very concerned about their fate and therefore would not be willing to implicate themselves in sensitive matters of interest such as WMD, in light of looming prosecutions. Debriefers noted the use of passive interrogation resistance techniques collectivelyby a large number of detainees to avoid their involvement or knowledge of sensitive issues; place blame or knowledge with individuals who were not in a position to contradict the detainee's statements, such as deceased individuals or individuals who were not in custody or who had fled the country; and provide debriefers with previously known information. However, the reader should keep in mind the Arab proverb: "Even a liar tells many truths."
