The UK Guardian is making good on its promise to release more information provided by Edward Snowden, revealing a Powerpoint presentation marked top secret, used to train NSA analysts in using the vast data gathering resources the agency provides. Glenn Greenwald writes: The files shed light on one of Snowden´s most controversial statements, made in his first video interview published by the Guardian on June 10. "I, sitting at my desk," said Snowden, could "wiretap anyone, from you or your accountant, to a federal judge or even the president, if I had a personal email".
