What is the role of an independent administrator in a photo array?

The role of an independent administrator in a photo array is primarily to conduct the witness identification without bias. This is crucial in ensuring the integrity of the identification process. An independent administrator, who is not involved in the investigation or related to the case, helps prevent any unintentional influence on the witness's decision. They are a neutral party who can administer the photo array in a manner that minimizes any suggestiveness, thereby increasing the likelihood that the identification will be reliable and free from contamination by the officer’s expectations or suggestions.

In contrast, preparing the photographs for presentation is typically a task for law enforcement personnel or support staff, not the independent administrator. Overseeing the questioning process is usually part of the responsibilities of investigators or officers directly involved with the investigation, rather than the independent administrator's role. Lastly, ensuring the officer's involvement would conflict with the purpose of having an independent administrator, as it could introduce bias into the identification process. The independence ensures that the witness feels free to make their identification without any pressure or influence from law enforcement personnel.
