Defendant Jeffrey Scott Nielsen appeals from a jury verdict finding him guilty of possessing a controlled substance with intent to distribute for value, a second degree felony. U.C.A., 1953, § 58-37-8(1)(a) (Repl.Vol. 6A, 1974 ed., 1985 Supp.). Nielsen argues that intentional misstatements in the affidavit supporting a search warrant for his residence rendered the warrant invalid under the fourth amendment to the federal constitution and required suppression of the evidence obtained pursuant to that warrant. He also argues that the information in the affidavit supporting the search warrant was insufficient to permit a finding of probable cause and that the trial court’s refusal to require disclosure of a confidential informant’s identity violated his due process rights. Although the officer’s misstatements were intentional and in bad faith, we find that the misstatements did not materially affect the magistrate’s finding of probable cause; therefore, the warrant must be sustained as a matter of federal law. Moreover, we find that the information in the affidavit supported the magistrate’s finding of probable cause and that the trial court did not err in refusing to require disclosure of the identity of the confidential informant. The conviction is affirmed.
On April 30,1983, Detective Harold Howard executed an affidavit which was used to obtain a search warrant for Nielsen’s *190residence. In the affidavit, Detective Howard stated that a confidential informant had told him that an individual living at Nielsen’s address and driving a car with a personalized license plate reading “Skydive” possessed one-half pound of cocaine valued at approximately $16,000. Detective Howard further stated that he had confirmed the informant’s tip and that he considered the informant to be reliable because the informant’s previous tips had led to the arrests of three individuals on drug-related charges.
A warrant authorizing a search for narcotics was issued and immediately executed. Nielsen was arrested after the search revealed that he possessed approximately 17.5 grams of cocaine, or just over one-half ounce. At a preliminary hearing, Detective Howard testified about the circumstances establishing probable cause for issuance of the warrant, repeating the statements contained in his affidavit.
After Nielsen was bound over for trial, the prosecution revealed that Detective Howard’s affidavit, which was the sole support for the search warrant, contained false statements. Contrary to his representations, both in the affidavit and at the preliminary hearing, Howard did not know the informant, had never had any personal contact with him, and had no personal knowledge of any facts relevant to the informant’s credibility. Instead, Detective Howard had been informed of the facts set forth in the affidavit and testified to at the preliminary hearing by another police officer, one Lieutenant Blair.
When the false statements came to light, Nielsen moved to suppress the evidence obtained in the search. Nielsen also moved the court for an order requiring the prosecution to identify and produce the confidential informant referred to in the affidavit. After a hearing, the trial court denied both motions in a minute entry. Nielsen proceeded to trial, where he was convicted of possessing a controlled substance with intent to distribute for value.
Before this Court, Nielsen first asserts that the intentional misstatements contained in Howard’s affidavit rendered the warrant invalid and the ensuing search illegal under the fourth amendment to the federal constitution. Accordingly, he argues that evidence obtained from that search should have been suppressed.
The overriding purpose of the fourth amendment’s provision prohibiting unreasonable searches and seizures is to safeguard personal privacy against arbitrary and unwarranted intrusions by governmental officials. E.g., Boyd v. United States, 116 U.S. 616, 624-30, 6 S.Ct. 524, 528-32, 29 L.Ed. 746 (1886); State v. Harris, 671 P.2d 175, 178 (Utah 1983). To that end, the Constitution provides that, with certain exceptions not relevant here, a search must be authorized by a warrant issued “upon probable cause, [and] supported by Oath or affirmation_” U.S. Const. amend. IV.
The responsibility for issuing warrants and for meeting the pertinent constitutional requirements that underlie their issuance rests with the magistrate, a neutral and detached party who independently determines whether probable cause exists to support a search. United States v. Jeffers, 342 U.S. 48, 51, 72 S.Ct. 93, 95, 96 L.Ed. 59 (1951); see State v. Hygh, 711 P.2d 264, 267 (Utah 1985). The interposition of a magistrate between the investigating officer and the person who is the object of the search is intended to limit the arbitrariness which might otherwise result if the determination of probable cause were left to the unbridled discretion of the police officer conducting the search. E.g., Johnson v. United States, 333 U.S. 10, 13-14, 68 S.Ct. 367, 368-69, 92 L.Ed. 436 (1948); State v. Harris, 671 P.2d at 178. Clearly, however, the magistrate can only fulfill his constitutional function if the information given to him is true; the obvious assumption behind the warrant requirement is that the factual showing to support a finding of probable cause will be truthful. United States v. Halsey, 257 F.Supp. 1002, 1005 (S.D.N.Y.1966), cited in Franks v. Delaware, 438 U.S. 154, 165, 98 S.Ct. 2674, 2681, 57 L.Ed.2d 667 (1978). Therefore, courts must be particularly vigilant in as*191sessing a claim that a police officer has misrepresented information in an affidavit supporting the issuance of a search warrant.
Nielsen argues that the search in this case was invalid under the legal principles espoused in Franks v. Delaware, supra. In Franks, the United States Supreme Court held that a defendant is entitled to an evidentiary hearing to challenge the validity of a search warrant if the defendant can establish that (i) an affiant in an affidavit supporting a search warrant made a false statement intentionally, knowingly, or with reckless disregard for the truth, and (ii) the affidavit is insufficient to support a finding of probable cause after the misstatement is set aside. 483 U.S. 171-72. By an extension of reasoning, the same test applies when a misstatement occurs because information is omitted; the affidavit must be evaluated to determine if it will support a finding of probable cause when the omitted information is inserted. See, e.g., United States v. Ippolito, 774 F.2d 1482, 1486-87 n. 1 (9th Cir.1985); United States v. Martin, 615 F.2d 318, 328 (5th Cir.1980); see generally 2 W. LaFave, Search and Seizure § 4.4 at 21-24 (1985 Supp.). If an affidavit fails to support a finding of probable cause after the false statements are excised or the omitted information is added, i.e., if the omission or misstatement materially affects the finding of probable cause, any evidence obtained under the improperly issued warrant must be suppressed. Franks v. Delaware, 438 U.S. at 156, 98 S.Ct. at 2676; United States v. Martin, 615 F.2d at 328; accord, e.g., United States v. Riccio, 726 F.2d 638, 641 (10th Cir.1984). The obvious purpose of Franks and its progeny is to avoid suppressing evidence when the actual facts, if known to the magistrate, would have resulted in a finding of probable cause. Deterrence of police misconduct is not to be a factor in the decision to suppress unless the misconduct materially affects the finding of probable cause.1
The State first contends that Detective Howard's false statements were not made intentionally, knowingly, or with reckless disregard for the truth, but were merely inadvertent technical errors attributable to his use of a standard form affidavit. This argument is entirely unpersuasive. A law enforcement officer must be aware not only of the need for accuracy in the information provided to a magistrate in support of an application for a search warrant, but also of the importance of absolute truthfulness in any statements made under oath. In this case, Detective Howard not only testified falsely in the affidavit, but repeated the perjured testimony in person and under oath at the preliminary hearing. We must conclude that Detective Howard’s testimony was knowingly false and that, as a matter of law, he acted in bad faith.
The State next contends that the warrant in this case is valid despite the false statement that Howard, rather than Lieutenant Blair, was personally familiar with the facts because the misstatement was immaterial. The State argues that warrants may be ■ issued upon double hearsay between police officers under the general rule that law enforcement officers are presumed to tell each other the truth; therefore, the falsehood in question was not material to the magistrate’s finding of probable cause. We agree.
*192The use of hearsay evidence to establish probable cause does not necessarily undercut the validity of a warrant. If the hearsay is reliable, and there is a substantial basis for giving it credence, it will support the issuance of a warrant. United States v. Harris, 403 U.S. 573, 580-81, 91 S.Ct. 2075, 2080, 29 L.Ed.2d 723 (1971); accord State v. Bankhead, 30 Utah 2d 135, 138, 514 P.2d 800, 802 (1973); State v. Treadway, 28 Utah 2d 160, 162-63, 499 P.2d 846, 847-48 (1972). In addition, there is a presumption that law enforcement officers will convey information to each other truthfully. See, e.g., United States v. Ventresca, 380 U.S. 102, 111, 85 S.Ct. 741, 747, 13 L.Ed.2d 684 (1965); McCormick v. United States, 309 F.2d 367, 372 (7th Cir.1962), cert. denied, 372 U.S. 911, 83 S.Ct. 724, 9 L.Ed.2d 719 (1963); People v. Leahy, 173 Colo. 339, 484 P.2d 778, 781 (1970); see generally 1 W. LaFave, Search and Seizure § 3.5(a) at 619-21 (1978). Therefore, double hearsay between police officers is not fatal on its face to the validity of a warrant.
Because of the presumption that police officers will be truthful in their communications with each other, and because double hearsay may support the issuance of a warrant, it is apparent that had Detective Howard revealed that the information was not a matter within his personal knowledge, but had been conveyed through another officer, there would have been sufficient information before the magistrate to support a finding that the informant was reliable.2 Therefore, under the reasoning of Franks, we must conclude that the falsehood was not material, and we must sustain the warrant as a matter of federal law.3
Our holding on this point disposes of Nielsen’s second argument — that the affidavit, when purged of the false statements, was insufficient to support a finding of probable cause. Given the totality of circumstances, with the omitted information inserted, the affidavit amply supported the magistrate’s finding of probable cause. See Illinois v. Gates, 462 U.S. 213, 230-31, 103 S.Ct. 2317, 2328, 76 L.Ed.2d 527 (1983).
Our upholding of the warrant under federal law should not be read as an endorsement of Detective Howard’s conduct or as. a determination of how the issue might be resolved under the Utah Constitution. As this case illustrates, the federal law as it has developed since Franks v. Delaware is not entirely adequate. There is no stronger argument for developing adequate remedies for violations of the state and federal *193constitutional prohibitions on unreasonable searches and seizures than the example of a police officer deliberately lying under oath in order to obtain a search warrant. See S. Kipperman, Inaccurate Search Warrant Affidavits as a Ground for Suppressing Evidence, 84 Harv.L.Rev. 825, 831 (1971). To allow a police officer to obtain a warrant utilizing false information tends to undermine respect for the legal system and to make the public cynical about the honesty and professionalism of those entrusted with law enforcement. As one commentator has observed, however, “[ejven though warrants issued on the basis of police perjury and warrants issued without probable cause are equally reprehensible, they are not equally unconstitutional.... Under Franks, evidence is to be excluded if, inter alia, the culpability of the affiant-officer destroyed probable cause,” but warrants based on perjury may be constitutional if probable cause otherwise exists. Comment, Franks v. Delaware: Granting the Right to Challenge the Veracity of Search Warrant Affidavits, 45 Brooklyn L.Rev. 391, 405 (Winter 1979).
Our decision about what the appropriate remedy might be if Nielsen had argued that the officer’s action violated his rights under article I, section 14 of the Utah Constitution is an open question. This Court has not decided whether an immaterial, intentional misstatement in an affidavit supporting a warrant requires suppression of the evidence as a matter of Utah law or whether it may give rise to some civil cause of action. It is worth noting, however, that the Utah Legislature has enacted a statute which provides a remedy for search and seizure violations under the Utah Constitution.4 See U.C.A., 1953, §§ 78-16-1 to -11 (Repl.Vol. 9A, 1977 ed., Supp.1985). In addition, the police officer may be liable for damages under the provisions of the federal Civil Rights Act, 42 U.S.C. § 1983 (1982). Cf. Malley v. Briggs, 475 U.S. -, 106 S.Ct. 1092, 89 L.Ed.2d 271 (1986).
Nielsen’s assertion that the trial court violated his due process rights when it failed to require the prosecution to disclose the identity of the confidential informant referred to in the affidavit can be quickly disposed of. As a matter of due process, the identity of a confidential informant must be disclosed only when such disclosure is “essential to a fair determination of the issues.” State v. Forshee, 611 P.2d 1222, 1224 (Utah 1980).5 The trial court must weigh several factors in determining whether to require disclosure: the defendant’s need for disclosure in order to prepare a defense, the potential safety hazards to the persons involved, and the public interest in preserving the flow of information from informants. Id. By necessary implication, a defendant must make some showing that disclosure of an informant’s identity is material and essential to his defense.
In this case, Nielsen argued merely that entrapment was “often a legitimate defense” in drug cases and that identifying the informant “[might] provide a critical element” in his entrapment defense. Nielsen did not assert that the informant was a material witness or a participant in the crime charged, nor did he make any factual showing that the informant could provide information relevant to his defense. Under these circumstances, he failed to overcome the government’s privilege against disclosure. See State ex rel. Collins v. Riddel, 133 Ariz. 376, 651 P.2d 1201, 1202 (1982); State v. Helfrich, 33 Wash.App. 338, 656 P.2d 506, 510 (1982).
The conviction is affirmed.
HALL, C.J., and HOWE and DURHAM, JJ., concur.. Prior to Franks, several circuits had held that even immaterial misstatements required suppression of the evidence if the misstatements were intentionally false. See, e.g., United States v. Carmichael, 489 F.2d 983 (7th Cir.1973); United States v. Thomas, 489 F.2d 664 (5th Cir.1973), cert. denied, 423 U.S. 844, 96 S.Ct. 79, 46 L.Ed.2d 64 (1975); United States v. Marihart, 492 F.2d 897 (8th Cir.1974), cert. denied, 419 U.S. 827, 95 S.Ct. 46, 42 L.Ed.2d 51 (1974). This reliance on the exclusionary rule certainly made it clear to police that the price for lying under oath in an attempt to deceive the magistrate would be high. The Supreme Court in Franks apparently concluded that the price set by these circuits was too high, and resolved the conflict by requiring exclusion of the evidence only when misstatements are knowingly or recklessly false and material. Following Franks, the adequacy of remedies for such blatant police misconduct under federal law remains unclear.
. In the present case, the falsity in the affidavit was Detective Howard’s representation that he had talked to the informant personally, when in fact it was Lieutenant Blair who knew the informant and conveyed the information to Howard. Presumably, Howard was unaware that he could rely on the hearsay from Blair in seeking a warrant and lied to the magistrate and the court in an attempt to cure what he preceived to be an evidentiary problem. Under these circumstances, it seems appropriate to analyze the affidavit for probable cause by adding the information improperly omitted. See United States v. Ippolito, 774 F.2d at 1486-87 n. 1.
. The dissent cites a case factually on point in support of its assertion that the misrepresentation was material and therefore required suppression of the evidence. See United States v. Davis, 714 F.2d 896 (9th Cir.1983). We believe that both the court in Davis and the dissent strain too hard to reach a result in declaring the misstatement material. It appears that both are motivated by a desire to reach wrongful police conduct regardless of the materiality of the misconduct. However, that use of the exclusionary rule is precisely what Franks repudiated. See n. 1, supra. It is apparent in both the Davis case and here that had the magistrate known the true facts, probable cause would have nonetheless been established. Cf. United States v. Jenkins, 728 F.2d 396 (6th Cir.1984).
Some courts have suggested a means for avoiding the result dictated by Franks by excluding evidence when intentionally false but immaterial statements were made in support of a warrant’s issuance. They have indicated that a court might rely on its general supervisory powers to exclude evidence seized in willful disobedience of the law when the evidence is not otherwise excludable under the fourth amendment. See United States v. Cortina, 630 F.2d 1207, 1214-16 and n. 5 (7th Cir.1980) (dicta); United States v. Barnes, 604 F.2d 121, 153 n. 17 (2d Cir.1979) (dicta), cert. denied, 446 U.S. 907, 100 S.Ct. 1833, 64 L.Ed.2d 260 (1980). We decline to follow this example, at least where federal constitutional questions are involved, because they are a direct avoidance of the governing fourth amendment case law.
. Although the legislature has recognized the need for some remedy for search and seizure misconduct by police, we express no opinion about the validity of the statute insofar as it attempts to otherwise limit the remedies available for violations of the federal or state constitutions.
. When State v. Forshee was decided. Rule 36 of the Utah Rules of Evidence contained an express provision concerning confidential informants. The rule has since been repealed, but the exception to the privilege against nondisclosure of a confidential informant’s identity continues to exist as a matter of due process.
