In THE SHADOW FACTORY, Bamford shows how the NSA’sfailure to detect the presence of two of the 9/11 hijackers inside theUnited States led the NSA to abandon its long-held policy of spyingonly on enemies outside the country. Instead, after 9/11 it turned itsalmost limitless ability to listen in on friend and foe alike over tothe Bush Administration to use as a weapon in the war on terror. Withunrivaled access to sources and documents, Bamford details how theagency has conducted domestic surveillance without court approval, andhe frames it in the context of the NSA’s ongoing hunt for informationabout today’s elusive enemies.
