Miranda v. Arizona (1966) led to which courtroom rule regarding confessions?

• A. Right to counsel
• B. Exclusion of improperly obtained confessions
• C. Double jeopardy protections
• D. Admissibility of eyewitness testimony

Answer: (B)

Miranda v. Arizona established that statements obtained during custodial interrogation must be preceded by clear warnings and a voluntary waiver of rights before they can be used in court. If those warnings aren’t given or the suspect doesn’t validly waive rights, the confession must be excluded from evidence. This is why the rule is about the exclusion of improperly obtained confessions: it protects the Fifth Amendment privilege against self-incrimination and ensures due process in interrogation.

Context helps: the decision arose after a suspect was questioned without being informed of his right to counsel or to remain silent, and a confession was obtained and used at trial. The ruling introduced the famous Miranda rights, tying police safeguards directly to the admissibility of confessions. While parts of the Miranda warnings (like the right to counsel) are important, the key courtroom rule addressed by the question is that statements obtained without proper warnings or voluntariness are excluded.
