If he's not going to pardon Scooter Libby, who is the victim of a political witch hunt, and a friend, he's not going to pardon two guys who were actually convicted by a jury for shooting a guy in the back and covering it up.
The guy was not shot in the back, but in the butt. Also, from what I hear some of the jurors stated that they did not hear all the facts and would not have voted to convict if they knew then what they know now.
