On Libby: To pardon or not to pardon?

I would take a presidential pardon of Libby as a show of arrogance making the White House immune to the Justice system.
That is the question of the day as the media, commentators and bloggers all have their say in the aftermath of Lewis "Scooter" Libby's conviction for lying to investigators during the probe into who leaked CIA officer Valerie Plame's name to the media in 2003.
As USA TODAY's Ken Dilanian writes, "With the ink hardly dry on ... Libby's perjury conviction, some conservatives are urging President Bush to wipe away the jury's finding of guilt by granting the former vice presidential aide a pardon."
New York Post columnist John Podhertz goes so far as to say it's a sure thing that Libby will eventually be cleared by the president:
Why? Because if Bush fails to pardon Libby, he will implicitly be accepting the contention that Scooter Libby was part of a White House conspiracy at the highest levels to destroy the career of a CIA agent whose husband had proved Bush & Co. had lied us into the Iraq War.
