You’d have to be an idiot to not think NSA was acquiring and keeping all information about and the content of electronic communications. You don’t build a million square foot building housing one large server/memory farm to save a couple of phone numbers and length of call or to/from email per electronic communication. Additionally, the collection is focused upon internal communications for domestic political and economic activities not foreign communications....the NSA and CIA have not given a single example of a terrorist attack prevented by their programs although multiple failures, in spite of their spying, are obvious and prevalent.
