Conducting a show-up within one hour after an incident is critical for maintaining the reliability and accuracy of eyewitness identification. This time frame is essential because it ensures that the witness's memory is still fresh, allowing them to recall details more clearly. Quick action also helps to reduce the chances of witness contamination or the blending of memories with others' accounts, which can occur if too much time passes.

In law enforcement practices, a shorter time frame for show-ups is often preferred, as research shows that the likelihood of correctly identifying a suspect decreases as time passes. While options that suggest longer time frames may acknowledge potential logistical challenges, they do not align with best practices for prompt identification procedures, which emphasize the importance of swift follow-up with witnesses.
