Mr. Chief Justice Burger
announced the judgment of the Court and an opinion in which Mr.- Justice Black and Mr. Justice Blackmun join, and in Part I of which [575] Mr. Justice Stewart joins, and in Part III of which Mr. Justice White joins.
We granted certiorari in this case to consider the recurring question of what showing is constitutionally necessary to satisfy a magistrate that there is a substantial basis for crediting the report of an informant known to the police, but not identified to the magistrate, who purports to relate his personal knowledge of criminal activity.
In 1967 a federal tax investigator and a local constable entered the premises of respondent Harris, pursuant to a search warrant issued by a federal magistrate, and seized jugs of whiskey upon which the federal tax had not been paid. The warrant had been issued solely on the-basis of the investigator’s affidavit, which recited the following: •
“Roosevelt Harris has had a reputation with me for over 4 years • as being a trafficker of nontaxpaid distilled spirits, and over this period I have received numerous information [sic] from all types of persons as to his activities. Constable Howard Johnson located a sizeable stash of illicit whiskey in an abandoned house under Harris’ control during this period of time. This date, I have received information from a person who fears for their [sic] life and property should their name be revealed. I have interviewed this person, found this person to be a prudent person, and have, under • a sworn verbal statement, gained the following information: This person has personal knowledge of and has purchased illicit whiskey from within the residence described, for a period of more than 2 years, and most recently within the past 2 weeks, has knowledge of a person who purchased illicit whiskey within the past two days from the house, has personal knowledge that the illicit whiskey is consumed by purchasers in the outbuilding known as and utilized as [576] the 'dance hall/ and has seen Roosevelt Harris go to the other outbuilding, located about 50 yards from the residence, on numerous occasions, to obtain the whiskey for this person and other persons.”
Respondent was subsequently charged with possession of nontaxpaid liquor, in violation of 26 U. S. C. § 5205 (a)(2). His pretrial motion to suppress the seized evidence on the ground that the affidavit was insufficient to establish probable cause was overruled, and he was convicted after a jury trial and sentenced to two years’ imprisonment. The Court of Appeals for the Sixth Circuit reversed the conviction, holding that the information in the affidavit was insufficient to enable the magistrate to assess the informant’s reliability and trustworthiness. 412 F. 2d 796, 797 (1969).
The Court of Appeals relied on Aguilar v. Texas, 378 U. S. 108 (1964), in which we held that an affidavit based solely • on the hearsay report of an unidentified informant must set forth “some of the underlying circumstances from which the officer concluded that the informant . . . was 'credible’ or his information 'reliable.’ ” Id., at 114. It concluded that the affidavit was insufficient because no information was presented to enable the magistrate to evaluate the informant’s reliability or trustworthiness. The court noted the absence of any allegation that the informant was a “truthful” person, but only an allegation that the informant was “prudent.” Having found the informant’s tip inadequate under Aguilar, the Court of Appeals, relying on Spinelli v. United States, 393 U. S. 410 (1969), looked to, the remaining allegations of the affidavit to determine whether they provided independent corroboration of the informant. The Court of Appeals held that the constable’s prior discovery of a cache on respondent’s property within the previous four years was too remote, and, [577] citing certain language from Spmelli, it gave no weight whatever to the assertion that respondent had a general reputation known to the officer as a trafficker in illegal whiskey.
For the reasons stated below, we reverse the judgment of the Court of Appeals and reinstate the judgment of conviction.

In evaluating the showing of probable cause necessary to support a search warrant, against the Fourth Amendment’s prohibition of unreasonable searches and seizures, we would do well to heed the sound admonition of United States v. Ventresca, 380 U. S. 102 (1965):
“ [T]he Fourth Amendment’s commands, like all constitutional requirements, are practical and not abstract. If the teachings of the Court’s cases are to be followed and the constitutional policy served, affidavits for search warrants, such as the one involved here, must be tested and interpreted by magistrates and courts in a commonsense and realistic fashion. They are normally drafted by nonlawyers in the midst and haste of a criminal investigation. Technical requirements of elaborate specificity once exacted under common law pleadings have no proper place in this area. A grudging or negative attitude by reviewing courts toward warrants will tend to discourage police officers from submitting their evidence to a judicial officer before acting.” 380 U. S., at 108.
Aguilar in no way departed from these sound principles. There a warrant was issued on nothing more than an affidavit reciting:
“Affiants have received reliable information from a credible person and do believe that heroin, map-[578] juana, barbiturates and other narcotics and narcotic paraphernalia are being kept at the above described premises' for the purpose of sale and use contrary to the provisions of the law.” 378 U. S., at 109.
The affidavit, therefore, contained none of the underlying “facts or circumstances” from which the mag’«trate could find probable cause. Nathanson v. United States, 290 U. S. 41, 47 (1933). On the contrary, the affidavit was a “mere affirmation of suspicion and belief” (Nathanson, supra, at 46) and gained nothing by the incorporation by reference of the informant’s unsupported belief. See Aguilar, supra, at 114 n. 4.
Significantly, the Court in Aguilar cited with approval the affidavit upheld in Jones v. United States, 362 U. S. 257 (1960). That affidavit read in pertinent part as follows:

“In the late afternoon of Tuesday, August 20, 1957, I, Detective Thomas Didone, Jr. received information that'Cecil Jones and Earline Richardson were involved in the illicit narcotic traffic and that they kept a ready supply of heroin on hand in the above mentioned apartment. The source of information also relates that the two aforementioned persons kept these same narcotics either on their person, under a pillow, on a dresser or on a window ledge in said apartment. The source of information goes on to relate that on many occasions the source of information has gone to said apartment and purchased narcotic drugs from the above mentioned persons and that the narcotics were secreated [sic] in the above mentioned places. The last time being August 20, 1957.” Id., at 267-268, n. 2.
