Double-Blind Photographic Identification Definition:

The presentation of an array of photos to a crime victim for the purposes of identifying the perpetrator, by an officer neither involved in the investigation nor aware of who the suspect is.

In order to prevent the suggestive nature of one versus others of an array of photos of suspects presented to a victim of crime for the purposes of identification of the perpetrator, police forces often ask an officer not associated with the investigation to make the presentation of the array of photos to the victim. The officer is double-blind because he/she does not know who the suspect is and is not involved in the investigation.

Justice Pellegrino, in State v Smith, wrote this:

"A double-blind photographic identification procedure is one in which the officer conducting the procedure has not been involved in the investigation and does not know who the target is."
