Fifth Amendment:
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
A properly warned suspect may waive his Miranda rights and submit to custodial interrogation. Miranda recognized that a suspect may voluntarily and knowingly give up his rights and respond to questioning, but the Court also cautioned that the prosecution bore a heavy burden
to establish that a valid waiver had occurred.1 The Court continued: [a] valid waiver will not be presumed simply from the silence of the accused after warnings are given or simply from the fact that a confession was in fact eventually obtained.
2 Subsequent cases indicated that determining whether a suspect has waived his Miranda rights is a fact-specific inquiry not easily susceptible to per se rules. According to these cases, resolution of the issue of waiver must be determined on ‘the particular facts and circumstances surrounding that case, including the background, experience, and conduct of the accused.’
3 Under this line of cases, a waiver need not always be express, nor does Miranda impose a formalistic waiver procedure.4
In Berghuis v. Thompkins, citing the societal benefit of requiring an accused to invoke Miranda rights unambiguously, the Court refocused its Miranda waiver analysis to whether a suspect understood his rights.5 There, a suspect refused to sign a waiver form, remained largely silent during the ensuing 2-hour and 45-minute interrogation, but then made an incriminating statement. The five-Justice majority found that the suspect had failed to invoke his right to remain silent and also implicitly had waived the right. According to the Court, though a statement following silence alone may not be adequate to show a waiver, the prosecution may show an implied waiver by demonstrating that a suspect understood the Miranda warnings given him and subsequently made an uncoerced statement.6 Further, once a suspect has knowingly and voluntarily waived his Miranda rights, police officers may continue questioning until and unless the suspect clearly invokes them later.7
The admissions of an unwarned or improperly warned suspect may not be used directly against him at trial, but the Court has permitted some use for other purposes, such as impeachment. A confession or other incriminating admissions obtained in violation of Miranda may not, of course, be introduced against him at trial for purposes of establishing guilt8 or for determining the sentence, at least in bifurcated trials in capital cases.9 On the other hand, the fruits
of such an unwarned confession or admission may be used in some circumstances if the statement was voluntary.10
The Court, in opinions that bespeak a sense of necessity to narrowly construe Miranda, has broadened the permissible impeachment purposes for which unlawful confessions and admissions may be used.11 Thus, in Harris v. New York,12 the Court held that the prosecution could use statements, obtained in violation of Miranda, to impeach the defendant’s testimony if he voluntarily took the stand and denied commission of the offense. Subsequently, in Oregon v. Hass,13 the Court permitted impeachment use of a statement made by the defendant after police had ignored his request for counsel following his Miranda warning. Such impeachment material, however, must still meet the standard of voluntariness associated with the pre-Miranda tests for the admission of confessions and statements.14
The Court has created a public safety
exception to the Miranda warning requirement, but has refused to create another exception for misdemeanors and lesser offenses. In New York v. Quarles,15 the Court held admissible a recently apprehended suspect’s response in a public supermarket to the arresting officer’s demand to know the location of a gun that the officer had reason to believe the suspect had just discarded or hidden in the supermarket. The Court, in an opinion by Justice Rehnquist,16 declined to place officers in the untenable position
of having to make instant decisions as to whether to proceed with Miranda warnings and thereby increase the risk to themselves or to the public or whether to dispense with the warnings and run the risk that resulting evidence will be excluded at trial. While acknowledging that the exception itself will lessen the desirable clarity of the rule,
the Court predicted that confusion would be slight: [w]e think that police officers can and will distinguish almost instinctively between questions necessary to secure their own safety or the safety of the public and questions designed solely to elicit testimonial evidence from a suspect.
17 No such compelling justification was offered for a Miranda exception for lesser offenses, however, and protecting the rule’s simplicity and clarity
counseled against creating one.18 [A] person subjected to custodial interrogation is entitled to the benefit of the procedural safeguards enunciated in Miranda, regardless of the nature or severity of the offense of which he is suspected or for which he was arrested.
