Law Enforcement Academy – Constitutional Law Practice Test

The concept being tested is how identification procedures work in practice. A show-up is a one-on-one confrontation between a victim or witness and a person suspected in the offense. It’s typically done quickly, often at or near the scene, to determine if the suspect is the perpetrator.

This distinguishes it from a formal lineup, where multiple individuals (including fillers) are presented to the witness to identify by comparison. A show-up is more immediate and less formal, which is why it’s described as a single-suspect presentation. It’s also different from a surveillance operation conducted after an arrest or a request for a search warrant, which serve different investigative purposes and aren’t identification procedures in the same sense.

So the best description captures the essential one-on-one, immediate nature of the procedure.
