NSA whistleblower Tom Drake talks Espionage Act, 9/11, intelligence with 60 Minutes

Thomas Drake worked for the National Security Agency before he was indicted by it. Drake felt that taxpayer money was being misused on unnecessary intelligence, not the information that would lead to the successful capture of terrorists.

While the government says he betrayed his country, Drake, facing 35 years in prison if convicted, says he only pointed out government mismanagement. Drake was imprisoned under the Espionage Act of 1917.

"The entire national security establishment - it was a failure, a fundamental systemic breakdown," Drake told "60 Minutes"' Scott Pelley in his first televised interview.
