During a field interview, if a subject decides to leave after being asked for ID, what should you do?

In a situation where a subject decides to leave after being asked for identification during a field interview, the appropriate action is to let them go. This aligns with the understanding that unless there is probable cause or reasonable suspicion to detain an individual, law enforcement cannot compel someone to stay or provide identification.

The fundamental principle here is the concept of voluntary interaction. If the subject chooses to leave and there are no specific legal grounds to detain them, law enforcement must respect that decision. It's important to maintain adherence to constitutional rights and ensure that any actions taken during the encounter are lawful and justified.

Additionally, detaining someone without proper justification can lead to legal issues, including accusations of unlawful seizure or violating the person's rights. Thus, allowing the individual to leave is both a legally sound decision and an important practice for maintaining trust and community relations.
