Who can act as a blind administrator in a photo array?

The role of a blind administrator in a photo array is crucial to ensuring the integrity of eyewitness identification. A blind administrator is someone who does not know the identity of the suspect and is therefore unable to inadvertently influence or bias the witness during the process of identification. This helps to maintain the objectivity of the identification procedure, as any prior knowledge of the suspect's identity could lead to unintentional cues or suggestions that might affect the witness's decision-making.

The correct answer emphasizes that any detective or sworn officer, provided they remain unaware of the suspect's identity, can fulfill this function effectively. This standard ensures that law enforcement personnel involved in the investigation are not affecting the outcomes of identification procedures, thereby enhancing the reliability of the process.

In contrast, individuals who have previously met the suspect or are involved in the case could introduce bias into the identification process, while restricting the role to only high-ranking officials or civilians unassociated with the case does not accurately reflect the flexibility that trained personnel can provide, given appropriate conditions.
