See, e.g., Wilkey, The Exclusionary Rule: Why Suppress Valid Evidence?, 62 Judicature 215 (1978); S. Schlesinger, Exclusionary Injustice (1977). For example, the Massachusetts Constitution of 1780 provided: "Every subject has a right to be secure from all unreasonable searches, and seizures, of his person, his houses, his papers, and his possessions. Only when a warrant is grounded upon an affidavit knowingly or recklessly false has the Court suppressed the evidence obtained as a result. . Although there are assertions that some magistrates become rubber stamps for the police, and others may be unable effectively to screen police conduct, see, e.g., 2 W. LaFave, Search and Seizure § 4.1 (1978); Kamisar, Does (Did) (Should) The Exclusionary Rule Rest on a "Principled Basis" Rather than an "Empirical Proposition"?, 16 Creighton L.Rev. and neutral magistrate is admissible in the prosecution's case in chief, even though a reviewing court has subsequently determined either that the warrant was defective, No. [Footnote 3/15] The judgment as to whether there is probable cause must be made in a practical and nontechnical manner. In the Court's view, the exclusionary rule was not one among a range of options to be selected at the discretion of judges; it was "an essential part of both the Fourth and Fourteenth Amendments." 565, 598-599 (1983); Mertens & Wasserstrom, The Good Faith Exception to the Exclusionary Rule: Deregulating the Police and Derailing the Law, 70 Geo. For a thoughtful examination of this point, see Schrock & Welsh, Up from Calandra: The Exclusionary Rule as a Constitutional Requirement, 59 Minn.L.Rev. Stripped of the authority of the warrant, the conduct of these officers was plainly unconstitutional -- it amounted to nothing less than a naked invasion of the privacy of respondents' homes without the requisite justification demanded by the Fourth Amendment. Instead, he acted without sanction of law, doubtless prompted by the desire to bring further proof to the aid of the Government, and, under color of his office, undertook to make a seizure of private papers in direct violation of the constitutional prohibition against such action. From the foregoing, it is clear why the question whether the exclusion of evidence would deter future police misconduct was never considered a relevant concern in the early cases from Weeks to Olmstead. . there is a fair probability that contraband or evidence of a crime will be found in a particular place. be seized and held and used in evidence against a citizen accused of an offense, the protection of the Fourth Amendment declaring his right to be secure against such searches and seizures is of no value, and, so far as those thus placed are concerned, might as well be stricken from the Constitution. Pp. In the ordinary case, an officer cannot be expected to question the magistrate's probable cause determination or his judgment that the form of the warrant is technically sufficient . . Until today, that has plainly not been the law; it has been well settled that, even when a magistrate issues a warrant, there is no guarantee that the ensuing search and seizure is constitutionally reasonable. 82-963 illustrates this point. We had to reorganize our thinking, frankly. I have no doubt that these decisions will prove in time to have been a grave mistake. 1365, 1369 (1983). If applied to judicial misconduct, the rule would be just as costly as it is when it is applied to police misconduct, but it may be ill-fitted to the job-created motivations of judges. The suppression of evidence obtained pursuant to a search warrant should be ordered only on a case-by-case basis and only in those instances where exclusion would promote the purposes of the exclusionary rule. But that price is one courts have often been required to pay to serve important social goals. The substantial social costs exacted by the exclusionary rule for the vindication of Fourth Amendment rights have long been a source of concern. Retraining sessions had to be held from the very top administrators down to each of the thousands of foot patrolmen.". The warrant was later determined to lack probable cause. See also LaFave, The Fourth Amendment in an Imperfect World: On Drawing "Bright Lines" and "Good Faith," 43 U.Pitt.L.Rev. [Footnote 3/29] If the police cannot use evidence obtained through warrants issued on less than probable cause, they have less incentive to seek those warrants, and magistrates have less incentive to issue them. This "defect" posed no risk of a general search. See J. Landynski, Search and Seizure and the Supreme Court 19-47 (1966); N. Lasson, The History and Development of the Fourth Amendment to the United States Constitution 53-98 (1937); R. Rutland, The Birth of the Bill of Rights 11 (rev. and Votes (by Seniority). However, the officer’s reliance must be objectively reasonable. 319, 322 ("Ah, but surely the guilty should not go free? 1 Annals of Cong. at 131, granted the motions to suppress in part. See this Court's Rule 21. Judges and magistrates are not adjuncts to the law enforcement team; as neutral judicial officers, they have no stake in the outcome of particular criminal prosecutions. . This paradox, as JUSTICE STEVENS suggests, see post at 468 U. S. 961-962, perhaps explains the Court's unwillingness to remand No. . See also Ervin, The Exclusionary Rule: An Essential Ingredient of the Fourth Amendment, 1983 S.Ct.Rev. Thus, what we. Had surveilled for a long period of time, and I believe his testimony -- and I think he said he consulted with three Deputy District Attorneys before proceeding himself, and I certainly have no doubt about the fact that that is true.". . Brinegar v. United States, 338 U. S. 160, 338 U. S. 180 (1949) (dissenting opinion). Ybarra v. Illinois, 444 U. S. 85, 444 U. S. 92 (1979); Lo-Ji Sales, Inc. v. New York, 442 U.

When that question is finally posed, I for one will not be surprised if my colleagues decide once again that we simply cannot afford to protect Fourth Amendment rights. United States v. Karathanos, 53 F.2d 26, 34 (1976). "[T]he general rule [is] that Fourth Amendment rights are personal rights which, like some other constitutional rights, may not be vicariously asserted.
