Everyone chill out; this is not over.
This is NOT the end of the investigation. Fitzgerald has NOT answered the question of whether a crime to out a CIA operative has been committed. That is why he is charging Libby with perjury NOW -- by the very nature of perjury he cannot find out the truth if people involved in the investigation are lying to him and
obstructing the process.
Remember those close to Fitz have said his method is to nab the small fish first and work his way up to the big ones. This perjury indictment is but Fitzgerald's way of moving towards the truth.
I think the (over)use of the term "Fitzmas" has created false expectations among some people that, during a single day, the whole regime would come crashing down in dramatic fashion with the Special Prosecuter's announcement. This is a slow, methodical, process -- and it should be. Just because Libby was the "only" one indicted today, doesn't mean it's over.
