In April 2000, FBI agent Ken Williams begins investigating an Arizona flight student named Zacaria Soubra with suspicious radical militant ties. Soubra will be the main focus of Williams’s July 2001 memo about suspect Middle Easterners training in Arizona flight schools (see July 10, 2001). But Williams’ investigation into Soubra is greatly slowed because of internal politics and personal disputes. When he returns to this case in December 2000, he and all the other agents on the international terrorism squad are diverted to work on a high-profile arson case. James Hauswirth, another Arizona FBI agent, will later say, “[Williams] fought it. Why take your best terrorism investigator and put him on an arson case? He didn’t have a choice.” The arson case is solved in June 2001 and Williams returns to the issue of Islamic militant flight school students. His memo comes out much later than it otherwise might have. Hauswirth will write a letter to FBI Director Mueller in late 2001, complaining, “[Terrorism] has always been the lowest priority in the division; it still is the lowest priority in the division.” Others insiders later concur that the Arizona FBI placed a low priority on terrorism cases before 9/11.
