The Forgotten Fifth Prong: A Critical Review of Dynamic Miranda Decision-Making during Interrogation

Abstract Miranda warnings were introduced to safeguard individuals during custodial interrogation by ensuring they are informed of their constitutional rights. While the first four prongs—such as the rights to silence and counsel—have been extensively examined, the fifth prong, which permits suspects to reassert or modify an initial decision during questioning, has received comparatively limited attention. This review addresses that gap by applying Wells’s framework, which distinguishes between estimator variables—factors outside the control of the legal system (e.g., suspect mental health, education, legal experience)—and system variables—factors within the control of law enforcement (e.g., Miranda delivery, interview conditions, invocation protocols). Understanding how these variables shape decision-making across the course of an interrogation offers useful insight into how suspects engage with their rights in practice. Certain procedural elements—such as the clarity of warnings or the ability to revisit prior decisions—can influence whether protections are effectively upheld. Ensuring that suspects have a fair opportunity to understand and apply their rights at all stages of interrogation is central to both constitutional compliance and professional practice. By identifying areas where procedural improvements could further support these goals, this paper offers practical recommendations for enhancing the effectiveness of custodial interviews. Attention to the fifth prong offers law enforcement professionals an opportunity to strengthen both investigative outcomes and the broader aims of justice.
