Let’s open a can of worms. What about all those Germans who were U.S. citizens when WWII broke out but still went back to Germany to fight against the Americans. Ummm. What about their “due process”?
Except this situation differs in that we’re not talking about uniformed soldiers killed in a combat situation, but rather a known U.S. citizen who is targeted, hunted, and assasinated. It’s clearly distinguishable.
I guess we should be glad there was ‘Miranda rights’ during the Civil War. Imagine each side having to read each other their ‘rights’ before shooting or bayoneting each other.
