Under our laws, he lost his American citizenship then and there. He was no longer under our jurisdiction but he was under the jurisdiction of the Yemeni courts.
He never lost his citizenship before he was executed. You're just trying in vain to excuse Obama's blatant disregard for the Constitution.
Your fellow leftists at Slate were more shocked at people like you cheering Obama and Holder than the actual assassination.
I suppose had Gov. Rick Perry ordered the state of Texas to immediately execute a citizen who was found standing over 10 bodies with a smoking assault rifle without receiving a fair trial you'd be applauding that too, huh?
Just the opposite - you hypocrites cry when someone is executed AFTER 20 years of trials and appeals.
