This is so simple. Is everyone in a developed country like the United States and the United Kingdom entitled to a fair trial? If your answer to that question is "yes", then this is a no-brainer. The guys knows, as well as the judge and the jury, that his tattoos are going to ensure that the jury loses their impartiality and that is going to result in a less than fair trial. Just because you don't like what someone else likes, as heinous as it is, doesn't mean that their rights should be eradicated. The judge did the right thing.
