The Report of the Joint Inquiry into the Terrorist Attacks of September 11, 2001 by the House Permanent Select Committee on Intelligence and the Senate Select Committee on Intelligence, which was formerly classified top secret, may now be downloaded from the Government Printing Office website here:
http://www.gpoaccess.gov/serialset/creports/911.html The report makes some mention of the FBI's use of polygraphs for counterintelligence purposes. At p. 163 (p. 215 of the PDF file), in discussion of an FBI confidential informant in San Diego (who has been publicly identified as Abdussattar Shaikh), the report states:
Quote:The informant has cooperated fully since September 11, agreeing to FBI interviews and to being polygraphed by the FBI. Although the informant's responses during the polygraph examination to very specific questions about the informant's advance knowledge of the September 11 plot were judged to be inconclusive, the FBI asserts this type of result is not unusual for such individuals in such circumstances.
According to an ABC News report by Brian Ross titled
"Avoidable Tragedy," Mr. Shaikh denies that his polygraph outcome was inconclusive:
Quote:The report also criticizes the FBI for questioning whether its informant, Shaikh, held back advance knowledge of the Sept. 11 plot. The FBI defended its decision, citing significant inconsistencies in his statements and inconclusive results from a lie detector test.
Shaik, however, insisted the results were not inconclusive. "I did not fail that lie detector test," he said.
The Joint Inquiry report also mentions the polygraph at p. 211 (p. 263 of the PDF file):
Quote:In April 2000, the Intelligence Community obtained information regarding an alleged Bin Ladin plot to hijack a Boeing 747. The source, a "walk-in" to the FBI's Newark office, claimed that he had learned hijacking techniques and received arms training in a Pakistani camp. He also claimed that he was to meet five or six persons in the United States. Some of these persons would be pilots who had been instructed to take over a plane, fly to Afghanistan, or, if they could not make it there, blow the plane up. Although [page 222] the source passed a polygraph, the Bureau was unable to verify any aspect of his story or identify his contacts in the United States.
