What Hilzoy said
I don’t do “what she said” posts often (actually never, come to think of it), but Hilzoy’s post on why we should prosecute war criminals, even if they were high-ranking members of the executive branch — especially if they were high-ranking members of the executive branch — pretty much covers it. This isn’t a partisan issue, unless you believe the rule of law shouldn’t apply to members of your own party.
