“George J. Tenet, director of central intelligence, warned Congress last year [on February 2, 2000] that terrorists were exploring how ‘rapidly evolving and spreading technologies might enhance the lethality of their operations.’ A number of groups, he said, are seeking germ, chemical, radiological or nuclear arms. Mr. Tenet added that operatives of Osama bin Laden…’have trained to conduct attacks with toxic chemicals or biological toxins.’ ”
