I'm in law school, so if I did happen to get a summons, I would be quickly excluded. Lawyers do not want jurors who actually know the law.
That's weird. In England, even barristers and judges can be summonsed.
Golden Rule to getting out of jury duty: suggest you're biased. "Oh, this is that murderer from the paper right?", "Aww he looks really nice", "Christ. He's got the paedo smile and everything.".
