How many photographs will an investigator secure for conducting a photographic display, including the suspect's photograph?

In conducting a photographic display, also known as a photo lineup, the typical practice is to include a total of eight photographs, which comprises the suspect's photograph along with seven fillers or decoys. The reason for including a minimum of six to eight photographs is to ensure that the witness or victim has a fair chance to identify the suspect among other individuals who resemble the suspect in appearance but are not involved in the crime.

Using eight photographs helps to maintain the integrity of the identification process by providing a sufficient number of non-suspect images that can help to reduce potential bias. The aim is to support accurate identification while minimizing the likelihood of false identifications. It's essential for investigators to adhere to these standards to uphold the legitimacy of the evidence that may be used in court. Therefore, securing eight photographs, including the suspect’s, is the accepted guideline in investigative procedures.
