Chilling legal memo from Obama DOJ justifies assassination of US citizens
In the US, laws against assassination and extrajudicial killing make no distinction between American citizens and others: Foreigners have the exact same protections as citizens. This goes for the Bill of Rights as well. (Aside, this explains why the NSA is only "supposed" to spy outside of the US. Wether the target is a citizen or not is technically irrelevant on this particular point)If you accept that the US is in a war with Al Qaeda, then it is in no way surprising that the US government would then attempt to kill members of that organization. And, again, whether the members are American or not is quite literally irrelevant.However, if the targeted individual is physically located within the US, then the US government is generally supposed to arrest them instead of assassinate them - and again this protects foreigners and US citizens alike.
