Regarding the Terrorist Surveillance Program, “NSA [National Security Agency] Director Mike Hayden later said publicly [on January 23, 2006] that the program had been ‘successful in detecting and preventing attacks inside the United States’ and that it was his ‘professional judgment that we would have detected some of the 9/11 al Qaeda operatives in the United States’ if it had been operational before the attacks.”
