Voir dire is the process of selecting a jury. This process occurs in those cases in which there is the need for a jury, as opposed to a bench trial where the judge serves as the jury. In the voir dire process, prosecutors and defense attorneys ask members of the jury pool questions to determine whether or not they want those jurors to remain on the jury pool. In federal court, the judge often asks most of the questions. For example, if a prospective juror clearly indicates that they are biased either for or against law enforcement officials that would send a clear signal to the attorneys as to whether they would want that juror to serve.
