LegalSpeak: Miranda v. Arizona (1966)

In these cases, we might not find the defendants’ statements to have been involuntary in traditional terms. Our concern for adequate safeguards to protect precious Fifth Amendment rights is, of course, not lessened in the slightest. In each of the cases, the defendant was thrust into an unfamiliar atmosphere and run through menacing police interrogation procedures. The potentiality for compulsion is forcefully apparent, for example, in Miranda, where the indigent Mexican defendant was a seriously disturbed individual with pronounced sexual fantasies….

Today, then, there can be no doubt that the Fifth Amendment privilege is available outside of criminal court proceedings and serves to protect persons in all settings in which their freedom of action is curtailed in any significant way from being compelled to incriminate themselves. We have concluded that without proper safeguards the process of in-custody interrogation of persons suspected or accused of crime contains inherently compelling pressures which work to undermine the individual’s will to resist and to compel him to speak where he would not otherwise do so freely. In order to combat these pressures and to permit a full opportunity to exercise the privilege against self-incrimination, the accused must be adequately and effectively apprised of his rights and the exercise of those rights must be fully honored….

The warning of the right to remain silent must be accompanied by the explanation that anything said can and will be used against the individual in court. This warning is needed in order to make him aware not only of the privilege, but also of the consequences of forgoing it. It is only through an awareness of these consequences that there can be any assurance of real understanding and intelligent exercise of the privilege. Moreover, this warning may serve to make the individual more acutely aware that he is faced with a phase of the adversary system—that he is not in the presence of persons acting solely in his interest.
