As he claimed to know, under a long ago ruling of the US Supreme Court, the provision of the Constitution which makes treaties part of the law of the land along with the federal Constitution, is interpreted as meaning only that the several states of the United States are legally bound to respect the treaty's terms.  Interestingly, by the Court's ruling, I learned from this fellow in the Dailykos that the US government--that is the federal government is not bound by any treaty from the moment that said treaty's terms come into conflict with a subsequently passed law of the United States.

Bullshit, or else I can't understand why Texas insists on flaunting the obligation to put any foreigner that is arrested for a crime in contact with the consular representation from their home country and nobody does anything about it. There are many cases of foreigners on death row who did not have proper legal representation and were never given the option to contact their embassy/consulate. I forget whether there have been any executions, but I think at least of Mexicans there have been.

A society committed to the notion that government is always bad will have bad government. And it doesn't have to be that way. — Paul Krugman
