At Racket News, Matt Taibbi provides some background information on FBI failures leading up to the 9/11 terrorist attacks:
On August 13, 2001, 33-year-old French citizen Zacarias Moussaoui paid $6,800 in $100 bills to train on a 747 simulator at the Pan-Am International Flight Academy in Eagan, Minnesota. A retired Northwest Airlines pilot named Clarence “Clancy” Prevost thought Moussaoui’s behavior was odd for someone with no pilot’s license and told his bosses as much. When they said Moussaoui had paid and they didn’t care, Prevost said, “We’ll care when there’s a hijacking and the lawsuits come in”.
The company went to the FBI and on August 16, in what should have been one of the biggest arrests in the history of federal law enforcement, Moussaoui was picked up on an immigration violation. Agents on the case wanted permission to search Moussaoui’s belongings, with one asking superiors as many as 70 times for help in obtaining a warrant. The situation grew more urgent when the French Intelligence Service sent information that Moussaoui was connected to Islamic radicals with ties both to Osama bin Laden and the Chechen warlord Khattab, and that even within this crowd, Moussaoui was nicknamed “the dangerous one”.
Coleen Rowley, the Chief Division Counsel for the Minneapolis Field Office, absorbed agents’ concerns quickly and was aggressive in asking superiors to seek a Foreign Intelligence Surveillance Act (FISA) warrant to investigate further. One of the goals was a look at Moussaoui’s computer, as agents believed he’d signaled he had “something to hide” in there. But unlike the former Northwest pilot Prevost, whose superiors trusted his judgment and escalated his concerns, Rowley and the Minneapolis field office were denied by senior lawyers at FBI Headquarters. The Bureau was sitting on the means to stop 9/11 when the planes hit the towers.
This story is actually worse than described, as Rowley made clear in what became a famous letter she wrote to then-Director Robert Mueller the following May. “Even after the attacks had begun,” she wrote, “the [Supervisory Special Agent] in question was still attempting to block the search of Moussaoui’s computer, characterizing the World Trade Center attacks as a mere coincidence with Misseapolis’ prior suspicions about Moussaoui.”
While the Bureau blamed 9/11 on a lack of investigatory authority, the actions of the Minnesota office showed otherwise. Rowley’s decision to confront Mueller with a laundry list of unnecessary bureaucratic failures made her perhaps the FBI’s most famous whistleblower. Her letter excoriated the Bureau’s Washington officeholders for failing to appreciate agents in the field, and for implicitly immunizing themselves against culpability.
