Scott Johnson collects some links to arguments favoring an immediate pardon. The argument against that is simply that, on appeal, Libby could be exonerated. A pardon now would moot the appeal and the chance for Libby to be cleared by the courts. I don’t think he should ever spend a day in jail, and if the appeal has not run its course by the time the president left office he should not do so without issuing the pardon, but the D.C. Circuit should have the chance to review Mr. Fitzgerald’s work before President Bush acts.
