Glenn Greenwald demolishes the right-wing argument that only citizens have constitutional rights
here.
...First, the U.S. Supreme Court, in 2008, issued a highly publicized opinion, in Boumediene v. Bush, which, by itself, makes clear how false is the claim that the Constitution applies only to Americans. The Boumediene Court held that it was unconstitutional for the Military Commissions Act to deny habeas corpus rights to Guantanamo detainees, none of whom was an American citizen (indeed, the detainees were all foreign nationals outside of the U.S.). If the Constitution applied only to U.S. citizens, that decision would obviously be impossible. What's more, although the decision was 5-4, none of the 9 Justices -- and, indeed, not even the Bush administration -- argued that the Constitution applies only to American citizens. That is such an inane, false, discredited proposition that no responsible person would ever make that claim.

The principle that the Constitution applies not only to Americans, but also to foreigners, was hardly invented by the Court in 2008. To the contrary, the Supreme Court -- all the way back in 1886 -- explicitly held this to be the case, when, in Yick Wo v. Hopkins, it overturned the criminal conviction of a Chinese citizen living in California on the ground that the law in question violated his Fourteenth Amendment rights to due process and equal protection. In so doing, the Court explicitly rejected what Susan Collins and many others claim about the Constitution. Just read what the Court said back then, as it should settle this matter forever (emphasis added):
The rights of the petitioners, as affected by the proceedings of which they complain, are not less because they are aliens and subjects of the emperor of China. . . . The fourteenth amendment to the constitution is not confined to the protection of citizens. It says: "Nor shall any state deprive any person of life, liberty, or property without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws." These provisions are universal in their application, to all persons within the territorial jurisdiction, without regard to any differences of race, of color, or of nationality; and the equal protection of the laws is a pledge of the protection of equal laws. . . . The questions we have to consider and decide in these cases, therefore, are to be treated as involving the rights of every citizen of the United States equally with those of the strangers and aliens who now invoke the jurisdiction of the court...
