Over the past two weeks, the Pulitzer and Polk awards have recognized the work of Glenn Greenwald, Laura Poitras, and other journalists responsible for bringing Edward Snowdens leaked documents to print. But one of the most high-profile TV reports on US surveillance was an uncritically supportive look from CBS and 60 Minutes. Today, PBS announced plans for a two-part Frontline special called United States of Secrets, which promises the definitive history of domestic surveillance since the September 11th attacks. The first part of the series, airing May 13th, is reported by Michael Kirk, who was recently awarded a Polk award for NFL concussion exposé League of Denial.
