He's certainly free to appeal on constitutional grounds to an appellate court. It appears his lawyer didn't even attempt to dispute the charges through motion work. What they were trying to do is tamper with the jury. The jury does NOT make rulings of law, it makes findings of facts. To ask otherwise would make you an enemy of the state and a shameful human being.
Have you ever noticed how fond you are of making inflammatory and melodramatic statements?
Who was trying to tamper with the jury? I believe it was a six person jury, 5 of which were women (more likely to be anti-gun) and 5 state workers (conflict of interest).
Sometimes you are so incredible I have to wonder if you believe what you're saying or if you're just simply marching to orders.
