If WikiLeaks had been around in 2001, could the events of 9/11 have been prevented? The idea is worth considering. There were a lot of us in the run-up to Sept. 11 who had seen warning signs that something devastating might be in the planning stages. One of us, Coleen Rowley, was a special agent/legal counsel at the FBI's Minneapolis division and worked closely with those who arrested would-be terrorist Zacarias Moussaoui on an immigration violation less than a month before the World Trade Center was destroyed. Following up on a tip from flight school instructors who had become suspicious of the French Moroccan who claimed to want to fly a jet as an ego boost," Special Agent Harry Samit and an INS colleague had detained Moussaoui. A foreign intelligence service promptly reported that he had connections with a foreign terrorist group, but FBI officials in Washington inexplicably turned down Samit's request for authority to search Moussaoui's laptop computer and personal effects. Later, testifying at Moussaoui's trial, Samit testified that he believed the behavior of his FBI superiors in Washington constituted "criminal negligence." WikiLeaks might have provided a pressure valve for those agents who were terribly worried about what might happen and frustrated by their superiors' seeming indifference.
