What harm would it do, exactly? Is there any objective evidence that the NSA has predicted anything or prevented anything?
As I understand it, they didn't know the Russians were planning to take Crimea, they didn't have actionable information on the Boston Marathon bombers despite explicit warnings from Russia and Germany, they didn't have a clue about the embassy attack in Benghazi.
Yet, they assert that spying massively on all Americans makes us safer. I remain wholly unconvinced and deeply skeptical.
