Bush Commutes Libby's Sentence

Our long national nightmare is over. Scooter Libby is reportedly having his sentence commuted by the President.

A quick logic question for conservatives. If giving amnesty to illegal aliens only encourages more illegal immigration, wouldn't it stand to reason that giving amnesty to Scooter Libby only encourages more lying under oath? Yeah, I know, you don't care about logice. Otherwise, you wouldn't be a conservative.
