In addition to throwaway4891a's comment, it seems a little against the whole spirit of the constitution and the mindset of the framers as stated in the declaration of independence to make the point that "non-citizens can have their rights violated" even if in this case the party was a citizen. The idea is we were to yield our inalienable rights to the state so that we could secure our life, liberty, and pursuit of happiness. The whole idea "well, they're not citizens, so it's okay" assumes that it is the government that grants rights, instead of the other way around.
