A juror is a person who is a member of a jury in a court of law. Jurors are selected to hear evidence presented during a trial and are responsible for making an impartial decision or verdict, typically determining whether a defendant is guilty or not guilty based on the facts of the case. They take an oath to be unbiased and follow the judge's instructions throughout the trial. Usually, a jury consists of 12 members, and their verdict often must be unanimous. Jurors play a crucial role in ensuring justice by acting as finders of fact in legal proceedings.
