As an FBI agent who specialized in counter-terrorism, John P. O’Neill investigated the bombing of the American embassies in Africa, the USS Cole in Yemen, the Khobar Towers in Saudi Arabia, and the first attack on the World Trade Center. O’Neill came to believe America should kill Osama bin Laden before Al Qaeda launched a devastating attack, but his was often a lonely voice. A controversial figure inside the buttoned-down world of the FBI, he was forced out of the job he loved and entered the private sector – as director of security for the World Trade Center.
