On the battlefield, bullets and bombs are all the due process that terrorists are entitled to — even if they are American citizens.
It is, which is why Lindh should be treated as an unlawful combatant, even though he is an American citizen.
However, the last time I checked, we don't currently have a war going on in Yemen. No troops on the ground, nobody firing at our troops. Yes, terrorists use "asymmetrical warfare," and we need to eliminate them before they hit us. But there's something especially repugnant about the US government putting an American citizen on a secret "hit list."
The constitution has a way of dealing with American citizens who have committed treason. I believe this scumbag has committed treasonous acts. But there's a procedure for dealing with treason, and it's NOT the President of the US ordering the death of that person. That's a tactic used by the old Soviet Union and its satellites, North Korea, and many other totalitarian states.
