I disagree. He was a foreign national inside the state of Texas committing a crime. The only “rights” he has are those enumerated in constitution and laws of the state of Texas for foreign nationals. If Texas law did not afford him the “right” to talk to the consulate, then he did not have that right.

Was the treaty actually ratified? There are an awful lot of treaties out there that we are 'signatories' to that haven't been through the ratification process.
