Liberal Jeff Rosen of The New Republic thinks the indictment of Libby is indefensible:

...it's important for journalists (including me) who vigorously opposed the Kenneth Starr investigation to state the obvious: The Fitzgerald indictments are an embarrassing confirmation of the old Washington rule that, when special prosecutors can't prove a crime, they indict the target for obstructing the investigation....Unlike the Starr investigation, moreover, the Fitzgerald investigation represents a disaster for the First Amendment and may do long—lasting damage to political discourse in Washington.
