The potential value of such anonymized domestic telephone records is best understood through a hypothetical example. Suppose a telephone associated with Mohamed Atta had called a domestic telephone number A. And then suppose that A had called domestic telephone number B. And then suppose that B had called C. And then suppose that domestic telephone number C had called a telephone number associated with Khalid Sheik Mohammed, the mastermind of the Sept. 11, 2001, attacks. The most effective way to recognize such patterns is the computerized analysis of billions of phone records. The large-scale analysis of anonymized data can pinpoint individuals -- at home or abroad -- who warrant more intrusive investigative or intelligence techniques, subject to all safeguards normally associated with those techniques.
