In eyewitness identification, which method is typically performed at the scene and may have reliability concerns due to at-scene conditions?

• A. Lineup at the police station.
• B. Interviews conducted later.
• C. Show-up at the scene.
• D. Photographic array selection.

Answer: (C)

Show-ups are used to quickly identify a suspect right at the scene. This method is performed on site, which makes it fast and actionable, but the reliability can be questionable because the eyewitness’s memory is shaped by the stressful, often chaotic environment. Factors like poor lighting, short viewing time, distance, weapon focus, and heightened emotions can distort perception and memory, increasing the chance of misidentification. In contrast, more controlled identifications—such as lineups conducted at the station, interviews conducted later, or photographic arrays—offer greater standardization and reduce on-scene biases. Recognizing the on-scene nature of a show-up helps explain why investigators must handle it with care and follow up with additional, more controlled identification procedures when feasible.
