Congress itself has been in on the lie the whole time to at least a small degree. Some willingly, and some perhaps not so much. Don't forget that this is exactly the sort of thing that Americans wanted the gov't to do, "keep us safe from the terrorists" I don't find the material leaked so far to be more compelling or worrying than prior leaks about the subject. The only difference I see so far is that the press suddenly cares, and that we've been promised more in the coming days. I do find it suspicious on the part of the gov't that there has been such a strong immediate effort to focus on and discredit Snowden, where prior leaks were almost ignored. But that's just my initial gut feeling.
