Honestly, I think any murderer deserves the death penalty.
Second preference, since we are "too enlightened" for that, they ought to serve life without parole.
So, I think he being denied parole is justice.
However, I find it interesting that because he shot someone that was "famous" he is apparently treated differently than if he shot some not famous.
Equal justice before the law. Unless, of course, you're famous. Some animals are more equal than others.
