If Valerie Plame was not a covert agent, and every known fact indicates that she wasn't, this entire investigation should be closed down now. I'm not interested in knowing who lied to the Grand Jury, even if it was Joe Wilson. I have no interest in people going to jail as a result of "Gotcha" games. If the identity of covert agents isn't at stake, then the entire investigation is a waste of time.
What if the confidentiality of national intelligence assessments is at stake?
