What action should be taken if a person becomes a suspect during an interview?

When a person becomes a suspect during an interview, it is crucial to stop the interview and read their rights. This action is mandated by the Miranda v. Arizona ruling, which established that individuals in custody have the right to be informed of their rights to remain silent and to have an attorney present during questioning. Once a person is identified as a suspect, they are considered to be in a situation where their freedom of movement is significantly restricted, thus requiring the protection of their Fifth Amendment rights.

Reading the rights ensures that the suspect is fully aware of their legal rights, which helps to prevent any self-incriminating statements made without knowledge of these rights. This process also serves to preserve the integrity of the investigation by ensuring that any statements made by the suspect can be admissible in court.

While other choices may seem relevant, they do not adequately address the necessary legal protocols required in such situations. Reassuring the individual may not adequately address their rights, continuing without interruption could lead to potentially inadmissible statements, and consulting a supervisor, while a good practice in some scenarios, does not replace the immediate obligation to inform the suspect of their rights.
