Lots of spirited debates going on about this. Liberals claiming it is wrong to kill this guy because he's American. Conservatives claiming it's wrong because Obama ordered it and they now have an ACLU alter-ego. Liberals claiming it's okay because Bush isn't doing it. Both sides citing the USC, UCMJ etc... So okay, here's the thing. This is about the fact that we now have an enemy without a politically defined boundary on a map somewhere. We didn't have that a couple hundred years ago unless you count indians and look what we did to them. So let's put it in a perspective that may offer some clarity. Let's say there was a COUNTRY of AlQaedia that you could point to on a map. That country was a religious theocracy run by whackjobs who declared war on lots of countries, including the USA. So if a US citizen moved there, became a citizen of AlQaedia, adopted their ways, joined their military, became a leading figure in that country's attacks against us and then was killed by a drone, what would people say? There would be no questioning the Constitutionality of it and his former status as a US citizen would not be a factor because he was now an AlQeadian. Enemy Combatant & Casualty of War, plain & simple. So that's exactly what happened. Al Qaeda has a political structure & government, public relations, defined heirarchy, military etc... And they have declared war on us and killed US citizens. The only difference is these particluar whackjobs don't have a country on a map somewhere. That is the only reason there is any argument over this.
