Who Outed Valerie Plame?

So far, I have stayed away from blogging on the Valerie Plame "outing". I have followed it somewhat, but others such as Captain Ed at Captain's Quaters and Powerline have done a superb job reporting and analyzing it. I have come to the general conclusion that it is really a non-story.

With that being said, I do have a question or two and a couple of thoughts I wanted to throw out into the blogosphere.

Jack Kelly asks, "Why is special prosecutor Patrick Fitzgerald pursuing so zealously the outing of CIA officer Valerie Plame, since it is all but impossible to prove that the leaker or leakers committed a crime?"

"The reporter Cooper is a free man because Rove gave him explicit permission to talk about their conversation. Miller, the reporter, is in jail because her source didn't; indicating he or she is someone other than Rove."

"Liberals want Rove's scalp." Why would Miller protect Rove, if he were the source since Rove is the one they are trying to bury with the allegations?

Kelly states, "Maybe Rove -- or someone else -- lied to the grand jury. Or maybe Fitzgerald is investigating a different crime. What if someone in the CIA was leaking classified information to influence the 2004 election?"

Uncovering that crime would be worthy of Fitgerald's zealous and dogged investigation.

Kelly postulates that the biggest shoe in this case hasn't dropped yet, and the liberal journalists won't like the results when it does.

Now for the kicker. Could the CIA leaker who outed Plame turn out to be Valerie Plame herself?
