From the links below:
Yesterday's indictment was dictated by time more than anything else. With the grand jury's term expiring today, if any indictment was going to be returned, this was the day, and I, for one, don't question Fitzgerald's statement that Libby's obstruction of the investigation prevented him from getting to the truth about the so-called "underlying" charges (e.g., those associated with outing a CIA operative). Indeed, the obstruction charged against Libby prevented the prosecutor from furnishing the one element of the underlying crimes that may be the most difficult to prove: mens rea, as it's known in the criminal law (i.e., a culpable state of mind). But, be assured: the last out in this game is still to come, and the indictment is a shot across the bow for a whole host of characters in this unfolding drama that should indicate to them sighs of relief would be premature.
First, we know that Fitz intends to continue the investigation, albeit with a new grand jury. That's no big deal, since the evidence that was presented to the first grand jury will be available, word-for-word and page-for-page, to the next one for their examination and, if necessary, for further elaboration or elucidation either by the prosecutor or by additional witnesses. In other words, the new grand jury won't be starting from scratch---not by a long shot.
Second, even the fact that Libby wasn't indicted for any of the possible classified-information-related offenses does't mean he still can't be, since the special prosecutor has the prerogative of getting a superseding indictment from the grand jury which is to follow
(not unlike what the prosecutor in Texas did in Tom Delay's case). Thus, Libby is still, technically under the gun, and the indictment itself is rife with indications that there is another shoe yet to drop, something Fitz also strongly foreshadowed in his responses to reporters' questions during his press conference. And, of course, neither Rove nor any of a variety of other characters whose participation was described in shadowy terms are, as yet, off the hook.
