What best describes show-up identification versus a lineup?

• A. Show-up is a quick identification of a single suspect; a lineup involves presenting multiple suspects or foils to a witness.
• B. Show-up uses multiple suspects.
• C. Lineups require a warrant.
• D. Show-up includes formal testimony.

Answer: (A)

In investigations, there are two common identification procedures with very different setups. A show-up is a rapid identification of a single person, usually conducted soon after the incident at or near the scene. The witness is shown just one person, which makes the process quick but highly suggestive.

A lineup, by contrast, presents several individuals—one suspect plus fillers or foils—to the witness in a controlled setting. This broader view helps the witness compare a range of people and reduces the chance of a mistaken identification by keeping the process more objective.

So the best description is that a show-up involves a quick identification of a single suspect, while a lineup involves presenting multiple suspects or foils to a witness. The other choices misstate either the nature of show-ups or lineup procedures, or introduce requirements (like warrants) that aren’t defining features.
