A Review of the FBI's Handling of Intelligence Information Related to the September 11 Attacks

[PDF - Redacted] In sum, we found individual and systemiic failings in the FBI's handling of information regarding the Hazmi andMihdhar matter. The FBI had at least five opportunJities to learn about their presence in the United States and to seek to find them before September 11,2001. Much of the cause for these lost opportunities involved systemic problems. We found information sharing problems be_veen the CIA and the FBI and systemic problems within the FBI related to counterterrorism investigations. The systemic problems included inadequate oversight and guidance provided to.FBI detailees at the CIA, the FBI employees' lack of understanding of CIA procedures, the inconsistent documentation of intelligence information received informally by the FBI, the lack of priority given to counterterrorism investigations by the FBI before September 11, and the effect of the wall on FBI criminal investigations.
