Perhaps it is just my interpretation of the unique grammatical constructions DevinSeay employs, but, for disputation, I would posit that DevinSeay's two statements contradict themselves.
Constitutional rights of an individual are not dependent on taxes nor a psycho-social sense of belonging.
There exist multiple Supreme Court precedents in which the court finds that the U.S. Constitution protects non-citizens (which I assume to be equivalent to the phrase "someone on the other side of the border").
One example is BOUMEDIENE et al. v. BUSH, PRESIDENT OF THE UNITED STATES, et al., argued December 5, 2007—decided June 12, 2008. In this recent case, the petitioners, who are not U.S. citizens, have the constitutional privilege of habeas corpus.
This is just one of many precedents in which the Supreme Court has found in favor of the Constitution protecting someone on the other side of the border.
