The judge will toss him off the jury for being too dominant a personality.
Personally, I was involved in a civil lawsuit and Anita Hill was in the jury pool. The judge excused her without even exposing her to voir dire.
Not to mention that as a member of the bar, no attorney in his right mind would let him through voir dire, he knows all the trade secrets. As soon as the lawyers find out that I have been a prosecutor, member of courts martial, president of courts martial, and president of a discharge proceeding of a homosexual Army Major that made it to the Supreme Court, I'm out of there. The defense attorneys won't take a chance.
