“Speaking at the Commonwealth Club in San Francisco seven months after 9/11 [on April 19, 2002], he [FBI Director Robert Mueller] insisted that ‘the hijackers left no paper trail. In our investigation, we have not uncovered a single piece of paper–either here in the U.S. or in the treasure trove of information that has turned up in Afghanistan and elsewhere–that mentioned any aspect of the September 11th plot.’ ”
