In my estimation, here is the necessary investigative direction required to get to the bottom of this entire tawdry affair:
1.Plame and her involvement in this entire fiasco
2.The CIA, its' intentional leaks and new found partnership with it's hereto-for neminis Democrat Party.
3. Joe Wilson, a has been, never was, political prostitute and the biggest already confirmed liar in the entire affair.
4.Fitzgerald himself. Perhaps his work on this was not nearly as good as his supposed reputation.

It appears as though Fitzgerald took for gospel all the accusations and ran off/chased down the supposed perpetrators. But, it looks to me, as it did from the beginning, that the accusations were more bogus than anything else and were just accepted as truth and never verified as true facts to begin with.

I would add to your list, why did the WH not assert that there was no outing, and that "darn tootin' we are trying to discredit Wilson."

Instead, the President of the United States adds gravitas to the whole bloody charade by calling it a "serious investigation."
