What is the typical purpose of a line-up in criminal procedures?

The typical purpose of a line-up in criminal procedures is to identify suspects. This process involves placing a suspect alongside other individuals (known as fillers or distractors) to allow witnesses or victims of a crime to observe and potentially identify the perpetrator. This tool is essential in the investigative process, as it helps to confirm or refute a suspect's involvement in a crime based on eyewitness testimony.

The effectiveness of a line-up relies on the careful selection of individuals included, ensuring that the suspect does not stand out inappropriately and that the process is conducted fairly. Accurate identification can provide critical evidence in court, aiding in the fair adjudication of cases and helping law enforcement focus their investigations on the correct individuals. Through this procedure, law enforcement can draw connections between the suspect and the crime based on eyewitness identification, which can have profound implications for the accused and the victim alike.
