When the jury comes into a courtroom, everybody rises. The lawyers, the defendant, the spectators, even the judge - they all stand up. There's a reason for that. It's a sign of respect.
Jurors are the most important people at the trial.
The lawyers have to complete law school, then pass the bar to be there. The judge has to do that, plus get elected or appointed. The defendants do unspeakable things to get into that room. That is, if they're guilty. A juror simply registers to vote.
