Miranda v. Arizona, the most famous of all self-incrimination cases, the Supreme Court imposed procedural safeguards to protect the rights of the accused. A suspect has a constitutional right not to be compelled to talk, and any statement made during an interrogation cannot be used in court unless the police and the prosecutor can prove that the suspect clearly understood that (1) he had the right to remain silent, (2) anything said could be used against him in court, and (3) he had a right to an attorney, whether or not he could afford one. If, during an interrogation, the accused requests an attorney, then the questioning stops immediately.
