Because Samit never made the explicit link to Afghan terror camps, the FBI could not claim a ‘foreign power’ was directing Moussaoui, the test for an intelligence warrant from the court. But had the bureau taken Samit’s fears of mayhem seriously, it could have sought a plain vanilla criminal warrant on Moussaoui based on probable cause. Samit was told that pressing too hard to obtain a warrant would hurt his career.

This decision not to seek a warrant gave rise to the myth that the ‘wall’ between overseas intelligence and criminal investigations made the PATRIOT Act necessary. This myth is cherished among right-wing radio talkers and has now morphed into a clumsy justification for the White House’s warrantless wiretaps. It is pure fantasy. Samit cited ‘obstructionism, criminal negligence and careerism’ by top FBI officials-not domestic spying restrictions-as the factors that stopped his investigation.
