Scenario: While working as a police officer, you respond to a robbery in progress involving two armed suspects at a liquor store. Upon arrival, you and your partner interview three witnesses to the crime. While conducting your investigation, another unit informs you they have a possible suspect detained several blocks from the incident.
Either using three squad cars or taking the witnesses over one at a time (but in some way keeping them separate when they view the suspect), I would give the three witnesses the chance to see the person being held. Some cars have tinted windows so the suspect cannot see who is identifying them. This would tell me whether to make a preliminary arrest and would justify a search of the suspect or their car/property. The other, more traditional way involves putting the suspect in a lineup and bringing the witnesses in one at a time at the station. While at the liquor store, I would also analyze the video of the crime (all such stores now have video security, for the most part) and see if the height and build matched the suspect. A photo lineup could also be used where photos of five people are taken and the witnesses are asked to identify who they think the robber was. The courts strongly disapprove of one person show ups, typically the suspect who has fled the scene is usually brought back so the witness can identify them. In doing this it tries to prevent an innocent person ending up in jail. If this method is used it requires very careful procedural safeguards. If there is one or more witnesses only one at a time should have access to the suspect. Warn or caution the witness that the suspect may not be on location, fully document both positive identifications and no identifications out comes that occur.
