I may be splitting hairs trying to find a silver lining (mixed metaphors, I know), but it seems to me without digging too deeply that this decision doesn't prohibit a life-without-parole sentence for a minor - only that a state may not enact a law requiring that sentence. I may be reading it wrong, or the author may be articulating it poorly, but from what I see, this is a blow against a mandatory life-without-parole for juvies, not a prohibition of the practice under all circumstances.
Oh, and "Kuntrell"? Anyone see a problem there?
