Why might police arrest someone if their identity cannot be confirmed?

The rationale for arresting someone when their identity cannot be confirmed primarily centers around the necessity of ensuring identification. When a person's identity is unclear, law enforcement may require detention to ascertain who the individual is, especially if there are concerns that the person may pose a risk to the community, themselves, or may have an outstanding warrant.

Ensuring the identification is crucial in the police's ability to perform their duties effectively, as it helps maintain accurate records and ensures that the individual can be appropriately processed according to the law. This is especially important in situations where the person may engage in behavior that could potentially lead to legal consequences or poses a threat, highlighting the need for proper identification before any further actions are taken.

Other options, while they may have some relevance to the broader context of police procedures, do not directly address the core reason for arresting someone lacking confirmed identity in this specific scenario. For instance, gathering evidence primarily pertains to investigations rather than initial identity confirmation, and processing the individual or implementing safety measures can occur after identification has been established.
