Try the death of a 16 year old American Citizen who was not attacking the U.S. at the time of his death by Drone overseas.
If Obama could order that, why wouldn't he order the same on American soil? After all, he believes he has the "authority" to issue secret "Kill on sight" orders without any review by anyone else.
A wanted individual who refuses to surrender and hides among others is responsible for the injury to others.
You wish to create a "shield" defense, but such won't hold up in court.
Remember that drones don't kill people, but that people kill people.
And you didn't answer the question.
If Obama can order the death of a 16 year old American Citizen by drone who was not in the process of attacking Americans, but merely eating dinner overseas, using your logic he can do the same thing here on American Soil.
You need a slight correction, the target of that drone strike was Anwar al-Awlaqi who was an American citizen. In the car with him was his 16 year old son who was NOT an American citizen and a friend who was not an American citizen. At the time of this killing Awlaki was not engaged in any terrorist activity. He was just driving down the road.
The question that this regime refused to answer is would they use the same tactics in this country that they use overseas. After 13 hours of filibuster, Rand Paul got the answer "No". This doesn't mean that a drone could not be used against someone actively engaged in some terrorist activity at that moment. It means that someone who is a non combatant could not be murdered on nothing more than the presidebt's whim.
