Obviously you believe your definition of “extraordinary circumstance” is the same as their definition of “extraordinary circumstance”.
I believe that there are “extraordinary circumstances” where the federal government can use lethal force against an American citizen whether that citizen is within or outside of the US.
I gave an example that no one has been able to refute until and unless you can disprove my example, my point stands. It doesn’t matter if the lethal force involves a drone or some other form of lethal force.
Also, as an aside, I believe Rand Paul to be only slightly more sane than his father. Rand Paul created a straw man argument where he made false claims about the position of the US Government.
