I'm pretty sure the US constitution disagrees with that premise, and should protect any US citizen from such a situation.

Personally - I'd like to see _much_ more transparency and accountability in the compilation and justification for most sorts of "government lists", and I fear the people in charge of "the kill list" which manages to kill people who are '… not “specifically targeted,”' have proven to be inadequately discriminating at the task…
Though I'd probably prefer not to have a "kill list". Killing should be limited to military personell in wars, during 'battle'. I realise the US has framed the war on terror in order to blur those lines... but seriously firing missiles into cafes!?
That's exactly what I responded to. I ignored your conclusion, because of your invalid premise.
Anyway, I 100% agree that "there is a burden of proof on me to explain why, by killing that someone my action is righteous, legal and moral"
