The claim that "justice" has been served [killing Bin Laden] is particularly murky. That is because "justice" can mean a number of things.
To Obama and much of the American public it apparently means an eye for an eye.
To human rights lawyers, it involves following procedural rules in meting out punishment, which explains the focus on the legality of the killings.
But to advocates and scholars of post-conflict justice, "justice" has a broader, sociological and empirically measurable meaning: the phenomenon of holding perpetrators accountable for crimes in the eyes of their victims. This concept has a normative package of ideas associated with it as well: accountability should be exercised not only consistent with the rule of law, but in a manner that promotes a human rights culture, minimizes or deters future atrocities, and promotes reconciliation and inter-group understanding.
Look, FLG would far rather discuss Justice than Fairness. He's said so on many occasions. Moreover, given that loves Plato, FLG is the last person who'd say What is Justice? isn't one of the most important questions we can ask. The issue here is this -- Osama bin Laden was a mass murderer and overall evil fucker. His death is Justice. No quotes.
