What is a photographic spread?

A photographic spread is specifically defined as a method used in law enforcement for identifying suspects through photographs. This process typically involves displaying a group of images of potential suspects to a witness or victim in a controlled manner, allowing them to identify the individual they recognize. This technique is critical in the investigative process, as it helps gather evidence while minimizing the chances of misidentification that can occur in live lineups.

In contrast, the other options describe different methods or tools used in criminal investigations. A physical lineup involves presenting live individuals to a witness, which can have a different set of challenges and implications. A written report of the crime serves to document details but does not aid in identifying suspects directly. An audio recording of witness statements is essential for gathering testimony but does not involve visual identification, which is the primary function of a photographic spread.
