How can one differentiate between a detention and a consensual encounter?

To differentiate between a detention and a consensual encounter, understanding the concept of voluntary interaction with law enforcement is key. A consensual encounter occurs when an individual willingly engages with a police officer without any coercion or threats. In such situations, the person has the right to leave at any time, which emphasizes the voluntary nature of the encounter. Therefore, option B correctly highlights that a consensual encounter allows for free departure without any obligation to remain.

In contrast, a detention implies a temporary restraint on a person's freedom for investigatory purposes, where the individual does not have the same level of freedom to leave. Detention is typically based on reasonable suspicion, leading to a situation where a person is not free to terminate the interaction. Understanding these distinctions helps illustrate why identifying the nature of the interaction—whether consensual or a detention—is crucial for both law enforcement and the rights of individuals involved.
