Miranda V. Arizona And Self-Incrimination Case Studies
1. Miranda v. Arizona (1966)
📝 Facts:
Ernesto Miranda was arrested and interrogated without being informed of his right to remain silent or to have an attorney present. He confessed to a crime, but later argued his confession was involuntary.
🔍 Legal Issue:
Does the Fifth Amendment’s protection against self-incrimination require law enforcement to inform suspects of their rights before interrogation?
Supreme Court Ruling:
Yes. The Court held that suspects must be informed of their rights to silence and counsel (now known as Miranda rights).
Confessions obtained without these warnings are inadmissible in court.
Significance:
Established Miranda warnings as a constitutional requirement.
Protects suspects from coercive interrogations and forced self-incrimination.
2. Salinas v. Texas (2013)
📝 Facts:
Salinas voluntarily answered some police questions but fell silent when asked about ballistics evidence before being arrested. Prosecutors used his silence against him.
🔍 Legal Issue:
Can a suspect’s silence during voluntary police questioning (before arrest or Miranda warnings) be used against them in court?
Supreme Court Ruling:
Yes, if the suspect does not explicitly invoke the Fifth Amendment right to remain silent.
Silence alone isn’t enough; suspect must clearly assert the right.
Significance:
Clarified limits of the right to silence before formal arrest.
Emphasized the need for explicit invocation of Miranda rights.
3. Berghuis v. Thompkins (2010)
📝 Facts:
Thompkins was given Miranda warnings but remained mostly silent during interrogation. After 3 hours, he answered a question, which was used to convict him.
🔍 Legal Issue:
Is a suspect’s silence considered an invocation of the right to remain silent, requiring police to stop questioning?
Supreme Court Ruling:
No. Silence is not an invocation of the right to silence.
Suspect must explicitly state they want to remain silent or have a lawyer.
Significance:
Reinforced that police can continue questioning unless rights are explicitly invoked.
4. J.D.B. v. North Carolina (2011)
📝 Facts:
J.D.B., a 13-year-old, was interrogated at school without Miranda warnings or a guardian present.
🔍 Legal Issue:
Does age matter in determining whether a suspect feels they are in custody for Miranda purposes?
Supreme Court Ruling:
Yes. Age is relevant when assessing if a reasonable person would feel free to leave (i.e., custody).
Miranda protections apply if a reasonable juvenile would feel deprived of freedom.
Significance:
Expanded Miranda’s scope by considering suspect’s age in custody analysis.
5. Dickerson v. United States (2000)
📝 Facts:
Congress passed a law trying to overrule Miranda by allowing certain confessions even if warnings weren’t given.
🔍 Legal Issue:
Can Congress overturn Miranda by statute?
Supreme Court Ruling:
No. Miranda is a constitutional rule, and Congress cannot supersede it.
Miranda remains binding precedent.
Significance:
Confirmed Miranda’s constitutional status and permanence.
6. Minnick v. Mississippi (1990)
📝 Facts:
Minnick requested counsel during interrogation. Police stopped questioning but later resumed without lawyer present.
🔍 Legal Issue:
Can police re-initiate interrogation without counsel once a suspect requests an attorney?
Supreme Court Ruling:
No. Police must cease interrogation until lawyer is present after a request.
Violation leads to suppression of statements made thereafter.
Significance:
Strengthened the right to counsel during custodial interrogation.
