What the FBI, and all security services are really interested in, is FUD. This is the same reason why they've never issued a denial about aliens at area 51, the same reason that they make random comments about truecrypt out of the blue, the same reason they've never released all the CCTV footage from the pentagon on 9/11 even though they could, the non denials around ECHELON, HAARP, etc. etc. etc. They'd much prefer people keep wasting energy guessing about the infinite space of "unknown unknowns" than spending time talking about the less titillating abuses that happen in plain sight.
