FBI Director Mueller states: “In our investigation, we have not uncovered a single piece of paper either here in the United States or in the treasure trove of information that has turned up in Afghanistan and elsewhere that mentioned any aspect of the September 11 plot.” He also claims that the attackers used “extraordinary secrecy” and “investigators have found no computers, laptops, hard drives or other storage media that may have been used by the hijackers, who hid their communications by using hundreds of pay phones and cell phones, coupled with hard-to-trace prepaid calling cards.” [Federal Bureau of Investigation, 4/19/2002; Los Angeles Times, 4/22/2002] However, before 9/11, CIA Director Tenet told the Senate that al-Qaeda is “embracing the opportunities offered by recent leaps in information technology” [US Congress, 3/21/2000] ; the FBI broke the al-Qaeda computer encryption before February 2001 [United Press International, 2/13/2001] ; witnesses report seeing the hijackers use computers for e-mail at public libraries in Florida and Maine [South Florida Sun-Sentinel, 9/16/2001; Boston Herald, 10/5/2001] ; in October 2001 there were many reports that hundreds of e-mails discussing the 9/11 plot had been found (see October 2001); Moussaoui’s laptop was found to contain important information (see (Late July-Early August, 2002)), and so on.
