Billmon has an excellect dissection of the journalistic ethics involved in the Plamegate leak. He even discusses the possible need for an act of civil disobedience if the circumstances involve a government that is performing crimes against humanity.
Of course, that possiblity is strictly theory in this case. He looks at Miller from a lot of angles, but eventually comes back to the original, most obvious conclusion as the most likely. We may know a lot more tomorrow, if Matt Cooper’s “Memoir of a Tool” is in the new issue of Time.
