6th Amendment: "In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence."
Not a word even implying that this applies only to US citizens.
Great point. If we forget that the Constitution does not give us rightd, but rather prevents government from violating our rights, then we’ve already lost.
