Libby's defense is to save Libby's butt....he will not accuse ANY of his 'superiors' of directly managing this Plame business......now if they (the investigators) want to infer anything and put 2+2 together, Libby can't be blamed, can he? Lordy, I'd love to be a fly-on-the-wall as the big boys juggle the various versions of "truth" they need to Gerrymander as this plays out!
