appear that maybe we should have taken some of these signals that were emanating, we shouldn't have treated them like noise. sometimes it's very difficult to distinguish between noise and signals, and obviously, looking back at things, you always have a clearer and more precise and complete picture. a lot of this is going to come out in the investigation. i think we're going to learn more and more as time goes on, with all the work that's being done at this particular time. but do i fault anybody right now for the way they handled things? i take the president's word for it and i also know that director clapper, the director, my successor, twice removed, of the directorate of national intelligence is also as a precautionary measure doing sort of a lessons learned post-mortem reviewing all the intelligence that was available and seeing if there might have been instances where we could have handled it differently.
