Well, of course, Karl Rove did it. He may not have violated the Intelligence Identities Protection Act of 1982, with its high threshold of criminality for outing a covert agent, but there's no doubt he trashed Joseph Wilson and Valerie Plame. We know this not only because of Matt Cooper's e-mail, but also because of Mr. Rove's own history.
