What would Snowden think of NSA chief's speech?

NSA Director Admiral Michael Rogers said Thursday that the nation needs to debate security versus privacy concerns in the wake of revelations of expansive government surveillance revealed by whistle-blower Edward Snowden.

In a wide-ranging speech at UC San Diego, which operates one of the nation’s largest computer science programs and is a leader in cybersecurity, Rogers contended that the Snowden revelations have hurt the National Security Agency’s counterterrorism efforts.

After Snowden, a former NSA contractor, leaked documents 18 months ago, Al Qaeda videos online warned terrorists to avoid certain communications methods “because the Americans are onto it,” Rogers said. “Don’t let there be any doubt from anybody in this room that these revelations have hurt our ability to conduct our mission,” he said. “As I look at ISIL and others, I’m watching those targets change their behavior directly because of this.”
