Justin wanted to be a juror on a criminal case but he was greatly disappointed when he was put on a civil case jury.
Selection of jurors is a very complicated process which takes a lot time, and several technical experts and jurists watch over the procedures flawless so that no misjudgement is passed.
In case of a grand jury, the jurors are given some brief instructions before they are put on a case, and during the trial, the judges guide them as to which point to be considered and which point to be ignored.
Though extreme care is taken to keep the jurors on any criminal case on trial from having any contact with the outside world, there are some unfortunate cases where some jurors are corrupted, and in such cases, the judges can ask for a fresh trial with a different jury.
