Okay, so again, we shouldn’t have taken out OBL then. He didn’t directly kill any Americans.
According to his own words he did, he was also present on the battlefield in Afghanistan and when the SEAL team came for him he had the opportunity to surrender. Due process was applied to him unlike many killed by the drone program.
You persist in avoiding my original point and digressing down these side issues. Constitutional restraints on the FedGov are not limited to American citizens. I know of no clause in it that makes exceptions to the law based on citizenship.
