4.11 Eyewitness Identification is a type of evidence used in criminal law, where the testimony of one or more witnesses is used to identify a suspect. Usually, this is done by comparing the witness's description of the suspect to a photo lineup or live lineup. There are two main types of 4.11 Eyewitness Identification: photo lineups and live lineups. In a photo lineup, the witness is presented with a set of photos of people who resemble the suspect, and is asked to select the one who matches the description they gave. In a live lineup, the witness is presented with a group of people who resemble the suspect, and is asked to identify the person they saw. Both types of 4.11 Eyewitness Identification have been used in criminal investigations for many years, and are still widely used in the United States. However, studies have shown that these methods are prone to mistakes, since witnesses may be influenced by other factors such as the photos presented or the other people in the live lineup. As a result, 4.11 Eyewitness Identification is often used in conjunction with other types of evidence, such as DNA analysis or security footage, in order to ensure the accuracy of the investigation.
