Witness testimonies are statements made by individuals who have seen or experienced an event, often used in legal settings. These accounts can provide crucial information about what happened, helping to establish facts in a case. Witnesses may be called to testify in court, where their observations can influence the outcome of a trial. The reliability of witness testimonies can vary, as factors like memory, perception, and bias can affect how events are recalled. Legal professionals, including lawyers and judges, assess the credibility of these testimonies to determine their significance in the context of a case.
