You say he was a traitor. Then let them prove that in a court of law, as the constitution so clearly requires. If he was a citizen then he was entitled to ALL the privileges thereof, regardless how overwhelming the government says the evidence against him was.
So you’re saying the law shouldn’t be able to shoot vicious criminals on site like Bonnie and Clyde? And whenever we find some criminal allied with a murderous, anti-U.S. group like Al-Qaeda, we should make sure we don’t kill any U.S. citizens who might be traveling with the group, right? And how do we do that?
The point of this nonsense is to eventually make it impossible for the U.S. to make war on anyone. We know who wants that. Don't fall for it.
