Rule of Law:
The testimony of a witness discovered through a defendant's voluntary statements, given after an incomplete Miranda warning, is not automatically subject to exclusion under the fruit of the poisonous tree doctrine because the failure to provide full Miranda warnings is a violation of a prophylactic rule, not a direct infringement of the Fifth Amendment right against compelled self-incrimination.
Facts:
- On April 19, 1966, a woman was found in her Pontiac, Michigan home, having been raped and severely beaten.
- A friend who found the victim, Luther White, noticed a dog in the house that did not belong to her.
- Police followed the dog from the victim's home to the house of Thomas W. Tucker.
- Police arrested Tucker and took him to the station for questioning.
- Before interrogation, police advised Tucker of his right to remain silent and his right to an attorney, but failed to inform him that counsel would be appointed for free if he was indigent.
- Tucker waived his rights and, in response to questioning, stated that he had been with Robert Henderson at the time of the crime.
- Police contacted Henderson, who contradicted Tucker's alibi and provided incriminating testimony, stating that he saw scratches on Tucker's face the next day and that Tucker made comments suggesting his involvement with a 'widow woman' nearby.
Procedural Posture:
- Thomas W. Tucker was convicted of rape in a Michigan state trial court, where the judge admitted the testimony of witness Henderson but excluded Tucker's own statements to the police.
- Tucker's conviction was affirmed by the Michigan Court of Appeals.
- The Michigan Supreme Court subsequently affirmed the Michigan Court of Appeals' decision.
- Tucker filed a petition for a writ of habeas corpus in the U.S. District Court for the Eastern District of Michigan.
- The District Court granted the writ of habeas corpus, concluding that Henderson's testimony was inadmissible as fruit of an unlawful interrogation.
- The State of Michigan, as petitioner, appealed to the U.S. Court of Appeals for the Sixth Circuit.
- The Sixth Circuit affirmed the District Court's judgment, upholding the grant of habeas corpus.
- The State of Michigan then petitioned the U.S. Supreme Court for a writ of certiorari, which was granted.

Issue:
Does the exclusionary rule require the suppression of a witness's testimony when the identity of that witness was discovered through a defendant's voluntary statements made after police provided deficient Miranda warnings?
Opinions:
Majority - Justice Rehnquist
No. The exclusionary rule does not require suppression of the witness's testimony. The police conduct did not abridge Tucker's constitutional privilege against compulsory self-incrimination, but rather departed from the prophylactic standards established in Miranda to safeguard that privilege. The Fifth Amendment prohibits compelling a defendant to be a witness against himself; it does not protect against the introduction of voluntary statements. Since Tucker's statements were voluntary and not coerced, the core constitutional right was not violated. The primary purpose of the exclusionary rule—deterring future unlawful police conduct—loses its force when the police acted in good faith under pre-Miranda legal standards. Furthermore, the derivative evidence, Henderson's testimony, is reliable and trustworthy, and the strong societal interest in admitting all relevant and trustworthy evidence at trial outweighs the minimal deterrent effect of excluding it in this context.
Concurrence - Justice Brennan
No. The judgment should be affirmed, but the Court's reasoning is unnecessary. The proper analysis is one of retroactivity. Under the principles of Johnson v. New Jersey, the full Miranda requirements should not be applied retroactively to exclude the 'fruits' of a pre-Miranda interrogation. The primary purpose of applying new constitutional rules retroactively is to enhance the reliability of the fact-finding process. Here, the derivative evidence is the testimony of a third-party witness, which is not inherently unreliable, unlike a potentially coerced confession. Therefore, the reach of Johnson should be confined to excluding the direct statements of an accused from a pre-Miranda interrogation, not the fruits derived from them.
Concurrence - Justice White
No. The judgment should be affirmed. While Miranda was ill-conceived, its prophylactic scope should not be extended to bar the testimony of third persons identified through admissions that are themselves inadmissible under Miranda. The arguable benefits of deterring police misconduct are far outweighed by the advantages of having relevant and probative testimony, not obtained by actual coercion, available at trial to aid in the pursuit of truth.
Dissenting - Justice Douglas
Yes. The witness's testimony must be suppressed. The failure to give the complete Miranda warning is a constitutional violation, not merely a departure from prophylactic standards. Miranda mandates that 'no evidence obtained as a result of interrogation' without adequate warnings can be used against the accused. Henderson's testimony is a direct 'fruit' of the unconstitutional police interrogation, akin to the suppressed evidence in Silverthorne and Wong Sun, and must therefore be excluded. The date of the interrogation is irrelevant; a defendant should not be deprived of the full protection of the Fifth Amendment based on an arbitrary calendar date.
Analysis:
This case significantly limits the scope of the Miranda exclusionary rule by distinguishing between violations of the Fifth Amendment right against self-incrimination itself (actual coercion) and violations of Miranda's judicially created prophylactic rules. By holding that the 'fruit of the poisonous tree' doctrine does not automatically apply to evidence derived from voluntary statements obtained in violation of Miranda, the Court created an exception that allows derivative evidence, such as witness testimony or physical evidence, to be admitted. This decision prioritizes the truth-seeking function of a trial over the deterrent effect of the exclusionary rule, particularly when police act in good faith and the resulting evidence is reliable. It has had a lasting impact, paving the way for further exceptions to Miranda's exclusionary rule, such as in Oregon v. Elstad and United States v. Patane.
