Well. An internal NSA audit exposed by the Washington Post reveals that the NSA violated privacy rules and broke the law “thousands of times per year” since 2008.
And, again, that is from an NSA internal audit. No telling what an impartial audit would find.
But don’t worry. The Dear Leader says (privately) that the NSA scandal is just “noise”. Nothing to see here. Trust your government! (And if you are not trusting your government, we’ll find out about it.)
