That's diplomatic immunity. As far as diplomatic considerations, they are zip in this case as the guy is NOT a foriegn national. Tx. on the other hand is tone deaf to diplomatic considerations, and just common sense on this stuff and it pissed me off when I lived there. Specifically there is a treaty called the Vienna Convention. It says that when a foriegn national is arrested they are to be advised that they have the right to make a call to their embassy. Texas ignored this on several occasions going so far as to execute a Mexican National who was never advised of that right. Now personally, I shed no tears, but treaties are based on quid pro quo. If we want an American popped in Mexico (or name your S hole country) to be able to let our embassy know what's going on, we have to do the same. In this case, given the guy was American and never a French resident or national ,and the woman married him knowing he'd killed his last SO (where do these women come from?) the French don't have a legal leg to stand on. They ask as a formality for a commutation, BO will deny it, and nothing will change.
