The 39-year-old had tried to appeal the sentence, but eventually withdrew the appeal in December. Speaking to People at the time of his sentencing, Diamond’s attorney Thomas Alberti said: "I've got to say I'm really proud of him, He gets it. I think he did the best that he could in the moment that he had to make the decision, but he certainly understands that you don't want to send the message to society that it should be the Wild West in a bar scene."
