The Supreme Court of the United States has already ruled that the president can extrajudicially murder american citizens, and that the Court does not have authority to overrule the President’s decisions on who they place on their terrorist watch list, AND that the president can drone strike those on the list without any input from Congress or the Courts. This means that any American citizen can at any point be murdered for being in the way of the President / Executive branch entirely legally. I dare you to find a more compelling political argument than “I can have your entire family incinerated from the heavens and you literally cannot defend yourself against that”.
