Season 20

1. Hunting Bin Laden

For years this one man has taunted, threatened and frustrated the United States. But who is he? The U.S. government has tried to link him to nearly every act of Islamic terrorism against Americans in the 90s: from the 1993 attack on the World Trade Center, to the bombings of U.S. military installations in Saudi Arabia, to the 1998 bombings of two US embassies in Africa.
