A new report in the New York Times by James Risen and Laura Poitras details how National Security Agency officials seeking dominance in intelligence collection, "pledged last year to push to expand surveillance powers," according to a top-secret strategy document leaked by Edward Snowden.
In a February 2012 paper laying out the four-year strategy for the N.S.A.’s signals intelligence operations, which include the agency’s eavesdropping and communications data collection around the world, agency officials set an objective to “aggressively pursue legal authorities and a policy framework mapped more fully to the information age.” Written as an agency mission statement with broad goals, the five-page document said that existing American laws were not adequate to meet the needs of the N.S.A. to conduct broad surveillance in what it cited as “the golden age of Sigint,” or signals intelligence. “The interpretation and guidelines for applying our authorities, and in some cases the authorities themselves, have not kept pace with the complexity of the technology and target environments, or the operational expectations levied on N.S.A.’s mission,” the document concluded.
