Does any reader know whether any media outlet has looked at NSA activity, as best as the public may know it, and how that activity squares with the Privacy Act of 1974?

I forget the search trail that led to this interesting Federal Registry entry [I decline to use social media of which others are enamored, including LinkedIn], but it is both interesting of itself, and as an example of something else [existence of a Privacy Act of 1974, of which I was previously unaware, but Nixon after all was Nixon and Watergate was Watergate]. It is all something I have not researched, it being a tedious prospect at best, but others might have an interest.
