I disagree with you, Dax. Let me ask...Should Medellin have been afforded a new trial on the basis that his right to consular access was violated? Even though that right was "violated" because Medellin not only failed to reveal he was a Mexican national and ask for access to his consular officials but Medellin actively portrayed himself as an American citizen?
That's not an easy question to answer, Lawmage.
From an emotional perspective, and my natural instincts that are horrified by his crimes, my immediate answer is that he should not have been afforded a new trial based on the denial of consular access.
However, you can look at it another way. The law is the law. The law is there to protect people. It cannot decide whether the person it is protecting is a good person or a bad person, if that person is a liar, or a cheater, or deceitful about his citizenship. And while it's true that the proecution would not be at fault for Medellin's failure to have consular visitation, if he didn't have it, for any reason at all, it can be argued that he is entitled to another trial.
That being said, there's almost no doubt that he'd be found guilty at the second trial as well, and the sentence would be the same. The question is do we respect the process of the law or don't we?
