Greenwald says: On NSA Claims About Misreporting of Two Slides.

It’s certainly possible that, like all journalists, we’ll make a mistake at some point. And if and when that does happen, we’ll do what good journalists do: do further reporting and, if necessary, correct any inaccuracy. But no evidence of any kind (as opposed to unverified NSA accusations) has been presented that this was the case here, and ample evidence strongly suggests it was not.

His “evidence” is complete nonsense, but it shows how he got it wrong. He reads things into the words that aren’t there.
