In fairness, can you name a time in WW2 where the US government intentionally killed US citizens without regard to due process? There is supposed to be a strict separation of never using the military against the citizens of the united states. We have the national guard for a reason. Capturing those targets wasn't an objective, the government wanted them dead and it didn't afford any of those American citizens the rights laid out in the constitution.
How is that any different than murder?
