Miranda v. Arizona, 384 US 436

​FACTS:
In the cases before us today, given this background, we concern ourselves primarily with this interrogation atmosphere and the evils it can bring. In No. 759, Miranda v. Arizona, the police arrested the defendant and took him to a special interrogation room, where they secured a confession. In No. 760, Vignera v. New York, the defendant made oral admissions to the police after interrogation in the afternoon, and then signed an inculpatory statement upon being questioned by an assistant district attorney later the same evening. In No. 761, Westover v. United States, the defendant was handed over to the Federal Bureau of Investigation by local authorities after they had detained and interrogated him for a lengthy period, both at night and the following morning. After some two hours of questioning, the federal officers had obtained signed statements from the defendant. Lastly, in No. 584, California v. Stewart, the local police held the defendant five days in the station and interrogated him on nine separate occasions before they secured his inculpatory statement.
 
ISSUE:
Is the privilege against self-incrimination fully applicable during a period of custodial interrogation.
 
RULING:
Yes. The circumstances surrounding in-custody interrogation can operate very quickly to overbear the will of one merely made aware of his privilege by his interrogators. Therefore, the right to have counsel present at the interrogation is indispensable to the protection of the Fifth Amendment privilege under the system we delineate today. Our aim is to assure that the individual's right to choose between silence and speech remains unfettered throughout the interrogation process. A once-stated warning, delivered by those who will conduct the interrogation, cannot itself suffice to that end among those who most require knowledge of their rights. A mere warning given by the interrogators is not alone sufficient to accomplish that end. 
 
1. The prosecution may not use statements, whether exculpatory or inculpatory, stemming from questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way, unless it demonstrates the use of procedural safeguards effective to secure the Fifth Amendment's privilege against self-incrimination.
 
(a) The atmosphere and environment of incommunicado interrogation as it exists today is inherently intimidating, and works to undermine the privilege against self-incrimination. Unless adequate preventive measures are taken to dispel the compulsion inherent in custodial surroundings, no statement obtained from the defendant can truly be the product of his free choice.
 
(b) The privilege against self-incrimination, which has had a long and expansive historical development, is the essential mainstay of our adversary system, and guarantees to the individual the "right to remain silent unless he chooses to speak in the unfettered exercise of his own will," during a period of custodial interrogation as well as in the courts or during the course of other official investigations.
 
(c) The decision in Escobedo v. Illinois, 378 U. S. 478, stressed the need for protective devices to make the process of police interrogation conform to the dictates of the privilege.
 
(d) In the absence of other effective measures, the following procedures to safeguard the Fifth Amendment privilege must be observed: the person in custody must, prior to interrogation, be clearly informed that he has the right to remain silent, and that anything he says will be used against him in court; he must be clearly informed that he has the right to consult with a lawyer and to have the lawyer with him during interrogation, and that, if he is indigent, a lawyer will be appointed to represent him.
 
(e) If the individual indicates, prior to or during questioning, that he wishes to remain silent, the interrogation must cease; if he states that he wants an attorney, the questioning must cease until an attorney is present.
 
(f) Where an interrogation is conducted without the presence of an attorney and a statement is taken, a heavy burden rests on the Government to demonstrate that the defendant knowingly and intelligently waived his right to counsel.
 
(g) Where the individual answers some questions during in-custody interrogation, he has not waived his privilege, and may invoke his right to remain silent thereafter.
 
(h) The warnings required and the waiver needed are, in the absence of a fully effective equivalent, prerequisites to the admissibility of any statement, inculpatory or exculpatory, made by a defendant.
 
2. The limitations on the interrogation process required for the protection of the individual's constitutional rights should not cause an undue interference with a proper system of law enforcement, as demonstrated by the procedures of the FBI and the safeguards afforded in other jurisdictions.
 
3. In each of these cases, the statements were obtained under circumstances that did not meet constitutional standards for protection of the privilege against self-incrimination.
