Jury selection is the selection of the people who will serve on a jury during a jury trial. The group of potential jurors (the "jury pool", also known as the venire) is first selected from among the community using a reasonably random method. Jury lists are compiled from voter registrations and driver license or ID renewals. From those lists, summonses are mailed. A panel of jurors is then assigned to a courtroom. The prospective jurors are randomly selected to sit in the jury box. At this stage, they will be questioned in court by the judge and/or attorneys in the United States. Depending on the jurisdiction, attorneys may have an opportunity to mount a challenge for cause argument or use one of a limited number of peremptory challenges. In some jurisdictions that have capital punishment, the jury must be death-qualified to remove those who are opposed to the death penalty. Jury selection and techniques for voir dire are taught to law students in trial advocacy courses. However, attorneys sometimes use expert assistance in systematically choosing the jury, although other uses of jury research are becoming more common. The jury selected is said to have been "empaneled". Voir dire Selected jurors are generally subjected to a system of examination whereby both the prosecution (or plaintiff, in a civil case) and defence can object to a juror. In common law countries, this is known as voir dire. Voir dire can include both general questions asked of an entire pool of prospective jurors, answered by means such as a show of hands, and questions asked of individual prospective jurors and calling for a verbal answer. In some jurisdictions, the attorneys for the parties may question the potential jurors; in other jurisdictions, the trial judge conducts the voir dire. The method and scope of the possible rejections varies between countries: In England, these objections would have to be very well based, such as the defendant knowing a potential juror, to be allowed. Some jurisdictions, including Australia, Canada, France, New Zealand, Northern Ireland, the Republic of Ireland, and the United States, give both the defense and prosecution a specific number of unconditional peremptory challenges. No justifications have to be brought to exclude a specific juror. Generally, defense attorneys exclude jurors who have professions or backgrounds similar to that of the victim and who could thus feel an emotional link to them, while prosecuting attorneys exclude
