The test of an intelligence officer is not so much the ability to accumulate information; it's to judge between different pieces of information, and not to take a piece of information and use it in a piece of analysis simply because it fits your case, but to use it because it either comes from a reliable source like signals intercepts, from a human source that has been vetted over time as a reliable person, or it comes from documentary information -- papers you've stolen from another government or some other organization. The work that came out of Feith's shop that I saw, especially on Al Qaeda and Iraq, was simply ... finding pieces of information in the world of intelligence information that fit the argument they wanted to make. Tenet, to his credit, had us go back 10 years in the agency's records and look and see what we knew about Iraq and Al Qaeda. I was available at the time, and I led the effort. We went back 10 years. We examined about 20,000 documents, probably something along the line of 75,000 pages of information, and there was no connection between [Al Qaeda] and Saddam.
