In the context of an arrest, a non-uniformed officer must show identification to ensure clarity and authority during the process. When arrests occur, it is crucial for the individuals involved, especially those enforcing the law, to establish their identity and authority, thereby preventing confusion or potential escalation in tense situations. A non-uniformed officer may not be immediately recognized as a law enforcement official, so presenting identification helps validate their role and actions during the arrest.

The other options do not hold as much relevance in this specific situation. A suspect is expected to comply with the arrest procedures but isn't required to show identification in the same way that an officer must. Bystanders and witnesses typically do not have an obligation to show identification during an arrest unless they are directly involved in an investigation. By focusing on the necessity for a non-uniformed officer to present identification, the answer emphasizes the importance of legitimacy and transparency in law enforcement actions.
