Following the arrest of Zacarias Moussaoui, the FBI fails to brief the Counterterrorism and Security Group (CSG) chaired by counterterrorism “tsar” Richard Clarke at the National Security Council (NSC) on the case. CIA director George Tenet will later say that briefing the CSG on such an arrest is “standard practice.” [Tenet, 2007, pp. 200] In July 2001, Clarke had told the FBI he wanted to be informed of anything unusual, even if a sparrow fell from a tree (see Shortly After July 5, 2001).
