Let's face it, he didn't exactly murder an entire family, molest any children, or gun down some Federal agents - so his crimes are totally inexcusable. He isn't Black, Latino, or a Kennedy, and therefore not above the law. Most of all, he hasn't made any outward displays of repentance, such as penning a children's book or contributing to the Clinton campaign. All Libby has offered in the way of an explanation for ruining Valerie Plame's life is that he has a lousy memory - but if there's a single paper cut on his genitals I have yet to see it.
This whole thing smacks of favoritism. Just another example of the elitist Repugnitards muddying the waters of a Judicial system we progressives have valiantly kept a nice yellowish hue for decades.
