If the Commonwealth of Virginia kills Malvo, the rule of law dies with him.
He was not sentenced to death, he was not eligible for a death sentence. That's the law. You or I might not like it, but it's still the law. Here in Virginia, we're very particular about our public servants obeying the law.
Perhaps you see things differently in Utah ...
No ... Malvo will live out his days rotting in prison. He will never see the outside of those cold grey walls ... never see the light of day or the bright cool green of springtime in Virginia without concrete and steel interrupting the view. It's a miserable existence, which he will escape only by death. Where he goes after he dies is above my paygrade.
It is enough.
I know, but we can always hope for an “accident”.
