What is a key difference between a lineup and a show-up?

• A. Lineups occur on-scene
• B. Lineups are done off-scene
• C. Show-ups involve a group of suspects
• D. Show-ups are always more reliable

Answer: (B)

The key difference between a lineup and a show-up lies in the location and context in which they are conducted. A lineup refers to a procedure where multiple individuals are presented to a witness or victim in a controlled environment, often at a police station, to establish whether any of them can be identified as the perpetrator of a crime. This method allows witnesses to make comparisons and assess their recollections of the suspect in a more formal setting. On the other hand, a show-up involves presenting a single suspect to a witness shortly after an incident occurs, often at the scene of the crime or nearby. This method is done in real-time to determine if the witness can identify the individual as the offender. The immediacy and context of a show-up mean that it is typically less structured than a lineup. Choosing the option that lineups are done off-scene correctly captures this fundamental difference in the processes and contexts of these identification methods.
