What is the purpose of a 'photo lineup' in investigations?

The purpose of a 'photo lineup' in investigations is specifically to assist witnesses in identifying a suspect from photographs. This technique is crucial in the investigative process as it allows witnesses to recall and recognize individuals who may have been involved in a crime without the pressure or suggestiveness of an in-person confrontation.

By presenting a set of photographs that include the suspect among others, investigators aim to obtain reliable identifications, which can be a key factor in building a case. The process is designed to minimize the chances of misidentification and enhance the accuracy of witness recall, ultimately supporting the pursuit of justice through corroborated evidence.

This method is not intended for entertainment, as it serves a critical role in the identification process. It also does not involve documenting crime scene evidence or distracting witnesses, both of which would detract from the primary goal of accurately recognizing and identifying potential suspects.
