When we were small children, we would put our thumbs against our noses and make various gestures with fingers. It was obvious and unmistakable.
President Bush appointed Judge Reggie Walton, because Judge Walton was a tough-on-crime, hard-as-nails, zero-tolerance, no-nonsense judge. President Bush appointed Judge Walton because Judge Walton espoused the philosphies of the right-wing Republican Party.
President Bush appointed Patrick J. Fitzgerald as a U.S. Attorney, because Fitzpatrick was a tough prosecutor with a good conviction record. The Department of Justice, full of Bush appointees, chose Fitzgerald as Special Prosecutor.
These tough-on-crime guys tried and convicted a good buddy of President Bush.
President Bush didn't like what these tough-on-crime guys did, because he didn't like the sentence personally. President Bush didn't like it that they picked on his good buddy.
So President Bush over-ruled it, giving his good buddy a "get out of jail free" card.
This is an authoritarian, autocratic, arrogant, elitist, socially and politically clueless nose-thumbing of a spoiled child of privilege. It is obvious and unmistakable.
