Why Care About Valerie Plame?

Those of my segment of the left may ask: Why care if a CIA agent is outed? Isn't this a positive thing?

Make no mistake: The CIA is a horrible institution. And the risks that CIA agents face is almost universally overblown by the media. But it is nonetheless a serious concern, and no person deserves to be put into harm's way in violation of the law.

Karl Rove and the others involved with this leak revealed the identity of Joseph Wilson's wife to silence Wilson and put pressure on other dissidents, plain and simple. When will we stand up to these new McCarthies and say, "Do you finally have no shame?"
