Discover why a former senior manager at the National Security Agency (NSA) made the difficult decision to reveal aspects of a secret surveillance program to the press, in this media gallery adapted from FRONTLINE. Following the September 11, 2001, terrorist attacks, Thomas Drake proposed that terrorists threatening America could be identified through a program that could gather international phone and email data but keep the identity of American citizens encrypted. After learning that the George W. Bush administration chose to implement the NSA program domestically with no privacy protection for Americans, Drake decided to join other government whistleblowers who questioned the legality of the program.
