I was amused to hear, yesterday, as I was driving in to work, that the NSA had identified all remaining documents that Edward Snowden took, and was going to proactively address the media about what is in those documents.
Two interesting things about this. One is that it admits that merely mentioning the existence of these programs is not, itself, a security threat. That's progress, of a sort.
The second, though, is that the NSA has no credibility in these matters. At every step, their MO has been to do one of lying, misleading, or outright denial. And every claim has been discredited, either with already-available info (such as the claim that there were 54 specific terror threats prevented with mass surveillance) or with other documents later released from the Snowden Cache.
So I can't say as I really care what the NSA claims, going forward. Nor, I think, should anyone else.
