As far as I know, constitutional rights apply equally to both citizens and non-citizens. Of course, if citizens aren't protected in this case, neither will non-citizens, but I think the distinction should not matter in constitutional matters.
I believe that current rulings indicate US Constitutional rights do not apply to non-citizens outside US borders.
Quote:
Citing Yick Wo v. Hopkins, the Court, in the case of Wong Wing v. US, further applied the citizenship-blind nature of the Constitution to the 5th and 6th amendments, stating ". . . it must be concluded that all persons within the territory of the United States are entitled to the protection guaranteed by those amendments,
(Note "within the territory of the United States")
