Appellant William Rhys Comstock (Com-stock) appeals his conviction, following a jury trial, of four controlled substance offense counts charged in two separate two-count indictments which were consolidated for trial. One indictment related to manufacturing and conspiring to manufacture methamphetamine on or about January 7, 1985 at the Lexington Hotel in San Antonio, Texas. The other indictment related to the manufacture, and the possession with intent to distribute, of methamphetamine on or about January 23, 1985 at the Ralph Barrios residence on Piper’s Run in San Antonio. Comstock’s sole complaint on appeal is that the district court erred in overruling his pretrial motion to suppress, and his trial objections to, the fruits of the January 23, 1985 search of the Barrios residence.
Comstock's challenge in this Court to the January 23, 1985 search is only on the ground that the warrant on which it was based was issued by a Texas justice of the peace, and that a Texas justice of the peace is not a judge of “a state court of record” as required by Fed.R.Crim.P. 41(a) for warrants issued thereunder. Comstock does not dispute that the justice of the peace was authorized under Texas law to issue the warrant, and that a warrant so issued does not violate the Fourth Amendment’s requirement of a neutral and detached magistrate. It is likewise undisputed that the warrant was requested by and issued to a San Antonio police department narcotics agent on the basis of an adequate showing of probable cause of a violation of Texas criminal law respecting methamphet-amines. However, Comstock claims, and the district court determined, that subsequent participation by federal agents in the search, which was foreseen when the warrant was obtained, required the application of Rule 41(a) in this federal prosecution, under our decisions in
Navarro v. United States,
I.
Comstock was prosecuted under two indictments consolidated for trial on charges that he conspired to manufacture the controlled substance methamphetamine in violation of 21 U.S.C. §§ 841(a)(1) and 846, and that he manufactured the methamphetamine on two occasions and possessed it with the intent to distribute in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2. One indictment — on conspiracy and manufacturing (Cause No. SA 85 CR 92) — pertained to his operation of a methamphetamine laboratory in the Lexington Hotel in San Antonio from on or before January 5, 1985, until on or about January 7, 1985. The other indictment — on manufacturing and possession with intent to distribute (Cause No. SA 85 CR 29) — involved the manufacture of methamphetamine occurring on or about January 23, 1985, in the home of Ralph Barrios on Piper’s Run in San Antonio. Comstock was convicted on all counts. 1
At trial, the prosecution produced evidence indicating that Comstock was a mo *1197 bile methamphetamine maker. 2 Using chemicals and equipment purchased over the counter at chemical supply houses, Comstock would move into a motel or residence for a few days, and, with the help of various accomplices, convert a bathroom into a functioning methamphetamine factory. After he had “cooked” a batch of the drug or performed an intermediate processing step, he would pack his materials into a vehicle and move on.
A. The Lexington Hotel
The Lexington Hotel laboratory was discovered virtually intact by law enforcement officials because of a manufacturing accident. After a guest at the Lexington complained of a foul odor, a hotel employee tried to enter a room whose registered occupant was one Gary Ackerson, but was denied access by the room’s occupants. Further guest complaints and the fear of a possible explosion caused the hotel management to call the fire department, and firemen entering Ackerson’s hastily vacated room discovered in the bathroom apparatus that resembled a chemical still. San Antonio police were notified, and Federal Drug Enforcement Administration (DEA) Agent Lee Phillips obtained a warrant to search the room, executing the warrant on January 7.
From the chemicals and equipment present, Agent Phillips and a DEA chemist concluded that the hotel bathroom had been the site of a working methamphetamine laboratory. Other miscellaneous evidence was found, including a scrap of paper bearing the words “Ralph # 95 Yellow cab” and a telephone number — without area code — labeled “home.” Although agents would later discover that Ralph Barrios, the owner of the Piper’s Run house, was a San Antonio taxi driver with the same telephone number, the DEA apparently did not discover Barrios’ involvement or identity through the Lexington Hotel search. At trial, however, both Ackerson and Barrios — arrested along with Com-stock in the Piper’s Run search — testified that the laboratory in the Lexington Hotel had been established and operated by Com-stock.
B. Piper’s Run
On January 22, 1985, a confidential informant told a San Antonio police narcotics officer, Detective Maurice Rose, that a methamphetamine laboratory was in operation at a residence on Piper’s Run in San Antonio. Detective Rose had previously received reliable tips from this informant, and believed the information was trustworthy. Rose was at that time assigned by the San Antonio police department (SAPD) to work with the DEA but still reported to the SAPD. He testified that the operational relationship between the two agencies was “an informal task force” and stated that he would ordinarily call in the DEA whenever he learned that a methamphetamine laboratory was involved. He also stated that it was customary practice for officers from both agencies to execute search warrants when a suspected laboratory was the target of the search. Detective Rose contacted Agent Phillips to tell him about the tip, and the two officers looked at the Piper’s Run house that same day to plan how a search could best be executed.
The next day, January 23, Detective Rose applied for a search warrant to a San Antonio justice of the peace, who then issued the warrant to Rose. As testimony at the pretrial suppression hearing revealed, justice of the peace courts were generally — albeit erroneously — believed to be courts of record by local law enforcement officers in San Antonio. 3
*1198 Rose testified that he knew he could obtain a valid state search warrant from a number of different state courts, including a municipal court conveniently located in the police department building downstairs from his own office, to which he ordinarily went for warrants. He stated that he was aware of the Rule 41 state court of record requirement and that his knowledge of that rule motivated him to seek a warrant not from the nearby municipal court — which he knew was not a court of record 4 — but, instead, from the more distant justice of the peace court, which he believed was a court of record. While he was preparing the warrant application, Detective Rose called DEA Agent Phillips and arranged for the state and federal officers to meet in the vicinity of the Piper’s Run residence, but he did not tell Agent Phillips which court would issue the warrant. However, Detective Rose did discuss the court of record requirement with his supervisor, SAPD Sergeant Pat Dotson, who confirmed that a justice of the peace court was a court of record. Sergeant Dotson testified, “It has always been the opinion of all the men in our offices that it was a court of record.”
Detective Rose claimed that, at the time the warrant was requested and until after it was executed, he intended to bring state charges against the defendants, but, after entering the Piper’s Run residence, he decided to turn the case over to the federal agents because he “just felt they were better qualified and better equipped to handle a case of this magnitude.”
There is nothing to suggest that the justice of the peace issuing the warrant believed, or had any reason to believe, that participation of federal officers in the search was likely or contemplated.
Rose further testified that when the warrant was executed some ten to twelve local police officers were present as well as at least three federal agents, including Agent Phillips. Detective Rose entered the Piper’s Run residence first. Those arrested in the house included Comstock, Barrios, and Ackerson. As the district court found, on adequate evidence, “Rose and other state officers ... entered the house and gathered the persons inside the living room area. Three federal agents, including Phillips, arrived during the execution of the warrant, and two more came later. The state officers conducted a cursory search of the residence and located the [disassembled methamphetamine] laboratory and other evidence.”
Then, Detective Rose, Sergeant Dotson, and Agent Phillips withdrew into an unoccupied bedroom to discuss who should take control of the evidence. Portions of Rose’s testimony indicate that he then told Phillips that the warrant was issued by a justice of the peace; at another place, Rose indicates that what he told Phillips was that he had gotten the warrant from “Judge Gutierrez” (there is no evidence that Phillips knew that Judge Gutierrez was a justice of the peace). Phillips’ testimony was that he did not look at the warrant, or ask to examine it, and that he did not know what court had issued it. In any event, the testimony of *1199 Rose, Dotson, and Phillips is unequivocal that both Rose and Dotson, in response to Phillips’ inquiries, assured Phillips that the warrant had been issued by a court of record. Moreover, Phillips’ testimony reflects that, although he was aware of the “court of record” requirement for federal warrants, and would not have proceeded with the search had he not been informed that the warrant had been issued by a court of record, he nevertheless did not know which Texas courts were courts of record, and would not then have known if a warrant had been issued by a court of record by looking at it. Phillips also testified that he was not aware that Texas justice of the peace courts were not courts of record until he was so informed the day before the suppression hearing. Although Phillips was otherwise an experienced DEA officer, and had assisted in some searches under state warrants, this was the first occasion on which he was the agent in charge of a search conducted under the authority of a state warrant. He had known Rose and Dotson for a considerable time and knew them to be officers who were knowledgeable in state law.
After these discussions with Rose and Dotson, Phillips then telephoned the Assistant United States Attorney to seek his approval for federal prosecution of the case. Although Phillips told the Assistant United States Attorney he had a valid warrant, he did not say — and was not asked — what court had issued the warrant. With federal prosecution authorized, Phillips then participated with the SAPD officers in a more thorough search. The district court found that Phillips “went into each room, labelled evidence and took photographs. The defendants and the evidence were placed into federal custody.” Charges were filed only by the federal agents.
The Piper’s Run search produced significant quantities of methamphetamine, as well as photographs taken inside the house showing ordinary household items apparently used in processing the drug. In addition, a bedspread from the Lexington Hotel, several chemicals used in making methamphetamine, and components of a portable laboratory were discovered packed into trunks in a pickup truck which Comstock claimed to own. The truck was backed into Barrios’ garage, its front visible from the street through the open garage door. During the search, the truck was unlocked by SAPD Officer Salazar with keys which he found inside the house in a pair of pants which Comstock indicated to Salazar were his.
C. Ruling Below
Comstock sought to suppress all evidence arising from the search, but his motion was denied after a pretrial suppression hearing. 5 The district court held that the search of the Piper’s Run residence was federal in nature because of the anticipated participation of federal agents, and that accordingly compliance with the standards of Rule 41 was required; that the justice of the peace court was not a court of record, thus rendering the warrant not in compliance with Rule 41(a); that this Court’s decisions in Navarro and Hanson required the exclusionary rule to be applied to the evidence seized; but that a good faith exception to the exclusionary rule was appropriate in this case, and that the evidence was therefore admissible.
With respect to the latter ruling, the district court found,
inter alia,
that “Rose and Phillips were acting in good faith”; that Rose and Dotson “believed the justice court was a court of record,” which was “the general belief at the police department”; that reasons for this belief included the facts that in the justice of the peace court in San Antonio, all cases, including search warrants, were assigned numbers and logged in a docket book, and a court reporter was present and proceed
*1200
ings were recorded
6
; that “Phillips did not know the warrant had been signed by a Justice of the Peace”; that Phillips, “who himself did not know which state courts are courts of record, asked the state officers [Rose and Dotson] if the warrant was issued by a court of record and relied on their representation that it was”; and, in effect, that had Phillips not been so informed and believed, he would have “declined to take the case.” These findings are findings of fact, whether or not the facts so found may be characterized as “ultimate,” and are hence reviewable under the clearly erroneous rule.
See Maine v. Taylor,
—U.S.-,
The district court further found that “[t]he reliance of the executing officers on the validity of the warrant was objectively reasonable.” This finding, as distinguished from the findings of the underlying facts on which it is based, is reviewable
de novo. United States v. Maggitt,
At trial, Comstock lodged timely objections to the admission of all evidence arising from the search, bringing the central issue in this case squarely before this Court.
II.
We have not been asked to decide whether Comstock’s Fourth Amendment rights have been infringed. Comstock does not claim that the search warrant was issued on other than a proper showing of probable cause, that the affidavit supporting it was false, that the issuing magistrate was insufficiently competent or neutral, or that the search was otherwise unreasonable. He contends only that evidence must be suppressed because the state court search warrant was not issued by a court of record as required by Rule 41(a).
On its face, Rule 41 appears to govern the validity of only federal search warrants requested by and issued to federal law enforcement officers, not of state warrants sought by and issued to local police, as occurred in this case:
“A search warrant authorized by this rule may be issued by a federal magistrate or a judge of a state court of record within the district wherein the property or person sought is located, upon request of a federal law enforcement officer or an attorney for the government.
“... The warrant shall be directed to a civil officer of the United States authorized to enforce or assist in enforcing any law thereof or to a person so authorized by the President of the United States_” Fed.R.Crim.P. 41(a) & 41(c)(1) (emphasis added).
Past decisions of this Court, however, have applied Rule 41(a)’s court of record requirement to exclude in a federal prosecution *1201 evidence obtained under an otherwise valid state search warrant, requested by and issued to state officers on a showing of state law violation, where the issuing court was not a court of record and federal officers participated in the search. 7
In
Navarro v. United States,
Byars
involved a state search warrant jointly executed by state and federal agents. The Supreme Court held that “[t]he warrant clearly is bad if tested by the Fourth Amendment,”
“While it is true that the mere participation in a state search of one who is a federal officer does not render it a federal undertaking, the court must be vigilant to scrutinize the attendant facts with an eye to detect and a hand to prevent violations of the Constitution by circuitous and indirect methods....
“... We cannot avoid the conclusion ... that the search in substance and effect was a joint operation of the local and federal officers....
“... The Fourth Amendment was adopted in view of long misuse of power in the matter of searches and seizures ... and the assurance against any revival of it, so carefully embodied in the fundamental law, is not to be impaired by judicial sanction of equivocal methods, which, regarded superficially, may seem to escape the challenge of illegality but which, in reality, strike at the substance of the constitutional right.” Id. at 249-50 (emphasis in original).
Lustig
reversed the refusal by a Court of Appeals “to suppress evidence claimed to have been seized in contravention of the Fourth Amendment.”
"To differentiate between [federal] participation from the beginning of an illegal search and joining it before it had run its course, would be to draw too fine a line in the application of the prohibition of the Fourth Amendment as interpreted in Byars....
“... [A] search is a search by a federal official if he had a hand in it; it is not a search by a federal official if evidence secured by state authorities is turned over to the federal authorities on a silver platter.... It is immaterial whether a federal agent originated the idea or joined in it while the search was in progress. So long as he was in it before the object of the search was completely accomplished, he must be deemed to have participated in it. Where there is participation on the part of federal officers it is not necessary to consider what would be the result if the search had been conducted entirely by State officers. Evidence secured through such federal participation is inadmissible_” Id. at 1373-
74 (emphasis added).
Under these precedents, the presence of federal officers “federalizes” a search conducted under a state warrant which violates constitutional rights. The Navarro panel forged the final link by extending the Byars and Lustig decisions to a Rule 41 case, though recognizing that Rule 41(a) looks to state law to determine whether a state court is a court of record.
Noting that “[t]he purpose of Rule 41 is to carry out the mandate of the fourth amendment,”
In requiring suppression,
Navarro
relied primarily on
Rea v. United States,
Navarro
also expressed the view that “continuance of the practice herein might well lead to a limited revival of the ‘silver platter’ practice” condemned in
Elkins v. United States,
The year following
Elkins,
the Supreme Court in
Mapp v. Ohio,
There are two subsequent
Navarro
decisions by this Court. In
United States v. Navarro,
After
Navarro,
in
United States v. Hanson,
We turn now to consider some other decisions of this Court which have addressed the Navarro rationale.
III.
Apart from Navarro and Hanson, we have not had occasion to suppress evidence on account of federal participation with state officers in the search and a failure to meet the requirements of Rule 41, where the authorizing state court warrant was valid under state law and the United States Constitution and was applied for by and issued to state officers on a showing of probable cause respecting a violation of state law. So far as Navarro was predicated on a desire to avoid the “silver platter” practice or, indeed, on a stringent application of the federal search doctrine exemplified by Lustig, it has been somewhat eroded in this Court.
*1204
In
United States v. Coronna,
In
United States v. Sellers,
“[E]very requirement of Rule 41 is not a sine qua non to federal court use of the fruits of a search predicated on the warrant, even though federal officials participated in its procuration or execution. The products of a search conducted under the authority of a validly issued state warrant are lawfully obtained for federal prosecutorial purposes if that warrant satisfies constitutional requirements and does not contravene any Rule-embodied policy designed to protect the integrity of the federal courts or to govern the conduct of federal officers.
“The proper test to be applied is whether a particular Rule 41 standard is one designed to assure reasonableness on the part of federal officers, or whether the provision merely blueprints the procedure for issuance of federal warrants.” Id. at 43-44.
On this basis, we “decline[d] to apply” to the warrant in question the “Rule 41 requirement” that the warrant be supported by a probable cause showing of a federal violation,
id.
at 44, a requirement we had previously invoked in
United States v. Brouillette,
*1205
We believe that we are bound by the holdings of
Navarro
and
Hanson
that, in the context of a case such as this, Rule 41(a) is applicable and its requirements have not been met.
Navarro
and
Hanson
further held that the evidence seized must be suppressed, in
Navarro
despite there being “no evidence of bad faith on the part of either the state or federal officers.”
IV.
Before turning directly to that subject, we briefly note the developments in other Circuits with respect to the exclusion of evidence obtained in instances where Rule 41 was found applicable but not complied with. By and large, these Courts have not required suppression. In
United States v. Burke,
“violations of Rule 41 alone should not lead to exclusion unless (1) there was ‘prejudice’ in the sense that the search might not have occurred or would not have been so abrasive if the Rule had been followed, or (2) there is evidence of intentional and deliberate disregard of a provision in the Rule.” Id. at 386-87 (footnotes omitted). 11
Cases involving the provision of Rule 41(c)(1) that search must be in the daytime unless the warrant “for reasonable cause shown” authorizes otherwise, are also instructive. In
United States v. Searp,
“[W]e think it important to differentiate between the right to be free from unnecessary and frightening intrusions by the State into our homes in the middle of the night and the procedures which have been established to protect that right.” Id. (emphasis in original).
Finding only the latter to have been violated, the Court declined to suppress. It also quoted with approval the passage from
Burke
set out above.
Respecting suppression for Rule 41 violations generally, in
United States v. Stefanson,
“[Ujnless a clear constitutional violation occurs, noncompliance with Rule 41 requires suppression of evidence only where,
“(1) there was ‘prejudice’ in the sense that the search might not have occurred or would not have been so abrasive if the rule had been followed, or (2) there is evidence of intentional and deliberate disregard of a provision in the Rule.”
In
United States v. Loyd,
V.
Turning now to
post-Navarro
and
Hanson
developments in Fourth Amendment exclusionary rule jurisprudence, in
United States v. Williams,
Thereafter, in
United States v. Leon,
“As yet, we have not recognized any form of good-faith exception to the Fourth Amendment exclusionary rule. But the balancing approach that has evolved during the years of experience with the rule provides strong support for the modification currently urged upon us. As we discuss below, our evaluation of the costs and benefits of suppressing reliable physical evidence seized by officers reasonably relying on a warrant issued by a detached and neutral magistrate leads to the conclusion that such evidence should be admissible in the prosecution’s case-in-chief.” Id. at 3416 (footnote omitted).
Plainly, Navarro and Hanson, which considered suppression the automatic consequence of violation of Rule 41(a), can no longer stand in light of Leon and Sheppard. Guided then by Leon, we must apply a “balancing approach” and evaluate “the costs and benefits of suppressing” the evidence.
VI.
We adopt the approach of Stefan-son and Loyd to the problem at hand, viz: a state court warrant, valid under state law, issued at the behest of and to state officers, on a probable cause showing of state law violation, where federal participation with the state officers in the search and possible federal prosecution were initially anticipated by the state officers and actually eventuated. Consequently, we hold that, where there is no constitutional violation nor prejudice in the sense that the search would likely not have occurred or been as abrasive or intrusive had Rule 41 been followed, suppression in these circumstances is not appropriate if the officers concerned acted in the affirmative good faith belief that the warrant was valid and authorized their conduct. Good faith in this context implies not only that Rule 41 was not knowingly and intentionally violated, but also that the officers did not act in reckless disregard or conscious indifference to whether it applied and was complied with. On the other hand, for these purposes, we do not mean by “good faith” that the officers’ conduct must be objectively reasonable.
We recognize, of course, that in
Leon
and
Sheppard
objective reasonableness was required to avoid suppression where the Fourth Amendment had been violated. Nevertheless, we believe that a less stringent standard is appropriate where, as here, we are not concerned with deterring unconstitutional conduct. The deterrence of
constitutional
violations has frequently been stressed in cases dealing with the exclusionary rule. As above-noted,
Calan-dra
and
Leon
both describe the exclusionary rule as “a judicially created remedy designed to safeguard Fourth Amendment rights.”
See Leon,
In our en banc decision in
United States v. Butts,
“The purpose of the exclusionary rule is to deter improper police conduct that violates a person’s reasonable expectation of privacy under the Fourth Amendment. It does not purport to reach all illegal conduct by officers....
“The exclusionary rule does not apply to deter wrongful or neglectful official conduct that does not involve a breach of the Fourth Amendment.” Id. at 1517-18, 1519 (footnote omitted).
We are not persuaded that
Mallory v. United States,
Finally, we note
Mallory’s
grounding in the proposition, established by
McNabb,
that “police detention of defendants beyond the time when a committing magistrate was readily accessible constituted ‘wilful disobedience of law.’ ”
Mallory,
“In large part when supervisory powers have been invoked the Court has been faced with intentional illegal conduct. It has not been the case that ‘[t]he criminal is to go free because the constable has blundered,’ People v. Defore,242 N.Y. 13 , 21,150 N.E. 585 , 587 (1926). In these cases there has been no ‘blunder’ by the Government agent at all; rather, the agent has intentionally violated the law for the explicit purpose of obtaining the evidence in question.”100 S.Ct. at 2451-52 . 17
*1210 Here, by contrast, we are being asked to let “the criminal go free,” not because of any intentional violation of law by the constable, but simply because the constable has “blundered” in the very sense spoken of by Justice Marshall. There being no constitutional violation, nor any prejudice in the Loyd and Stefanson sense, we are unwilling to take this step in the present context. 18
Our evaluation of the costs and benefits of suppressing this highly reliable physical evidence leads us to the conclusion that suppression is not warranted. A trial is, after all, primarily a search for the truth, and society has a strong interest in the conviction of those who have broken its criminal laws. Deterrence of official illegality, and preserving judicial integrity, are also important considerations. But here each weighs much less heavily as the violation is neither of constitutional dimensions nor intentional. Further, there is no prejudice to substantive rights of the kind alluded to in Loyd, Stefanson, and Searp. While our holding may “put a premium” on ignorance, we think that realistically any such premium is very small in this character of case, considering especially that we do not countenance conscious indifference or reckless disregard; the costs of suppression, in our view, weigh more heavily in the scales.
Following the rule of Loyd, Stefanson, and Searp, as above-explicated, we hold that the district court did not err in refusing to suppress or exclude the evidence secured by the challenged search. The judgment below is accordingly affirmed.
AFFIRMED.
Notes
. Comstock was sentenced to concurrent terms of nine years followed by a special parole term of five years on each of the two counts in Cause No. SA 85 CR 29, relating to the January 23 offenses. He was sentenced to concurrent nine-year terms on each of the two counts in Cause No. SA 85 CR 92, relating to the January 7 offenses, with a special parole term of five years *1197 on the second (manufacturing) count in that indictment. The sentence on both counts on Cause No. SA 85 CR 92 was made consecutive to the sentence on each count in Cause No. SA 85 CR 29, so that Comstock’s total sentence was eighteen years followed by a ten-year special parole term.
. In sustaining the district court’s denial of a pretrial motion to suppress, we may consider not only the evidence at the pretrial suppression hearing but also that at the trial itself.
See United States
v.
Quiroz-Carrasco,
. This misconception was shared by the justice of the peace court’s assistant court clerk, who testified that when the warrant was issued she was certain the court was a court of record, and that she learned it was not only twenty minutes
*1198
before she testified in the pretrial hearing. However, Fed.R.Crim.P. 41(a) relies on state law for the determination of whether a particular court meets the court of record requirement, and a justice of the peace court does not meet this standard under Texas law.
United States v. Hanson,
. The reliance of Rule 41(a) on state law for classifying courts as "courts of record” renders the status of qualifying state courts subject to change at the action of state legislatures. The Texas legislature has recently conferred court of record status, to some degree, on municipal courts in some Texas cities.
See
Tex.Gov’t Code §§ 30.001-30.404 (Vernon Pamphlet 1986). However, Texas municipal courts were not courts of record in the past, nor are most of them now.
See Navarro
v.
United States,
. No question concerning Comstock’s standing to complain of the January 23 search has been raised, either below or before this Court; nor did the district court address the matter in any way. We assume, arguendo, that Comstock had standing. Further, as we hold that the district court correctly declined to suppress the fruits of the January 23 search, we do not reach the question of whether, had the district court erred in this respect, such error would have been harmless, particularly as to the January 7 offenses.
. The evidence showed this was sometimes done by tape recorder in lieu of a court reporter.
. Apart from any application of Rule 41(a), this warrant would have been clearly valid. The Constitution does not require special qualifications, other than neutrality, of those who issue search warrants.
Shadwick v. City of Tampa,
. For example,
Lustig
states, "It is immaterial whether a federal agent originated the idea or joined in it while the search was in progress. So long as he was in it before the object of the search was
completely
accomplished, he must be deemed to have participated in it.”
. We are not wholly persuaded by this characterization of Navarro: the nature of the court that issued the warrant does not speak to the conduct of the search; the Brouillette requirement, not applied in Sellers, is no less substantive than the court of record requirement, which appears to be a procedural means to enhance the likelihood either of warrants being issued only on probable cause determined by a neutral magistrate or of being able to later determine whether they were so issued.
.We also observe that in 1972, subsequent to the searches involved in
Navarro
and
Hanson,
Rule 41(a) was amended to add the clause providing that the warrant be issued "upon request of a federal law enforcement officer or an attorney for the government.” Rule 41(c)(1) states that the warrant "shall be directed to a civil officer of the United States" or to a person authorized by the President; while this provision was in effect when
Navarro
and
Hanson
were decided, neither opinion adverts to it.
*1205
These provisions suggest that a state court warrant issued at the request of state officers only, directed only to such officers, and based on a probable cause showing of a state law violation, is not intended to be governed by the provisions of Rule 41. Nothing in Rule 41 states that it is applicable to such a warrant, or becomes so because federal officers participate in the search.
See, e.g., United States v. Searp,
.
Burke
distinguished
Navarro,
qualifying the above-quoted pronouncement by stating, “[E]xcept in a case like
Navarro
where, if the court was right in holding that Rule 41 applied, the defect made what was done an unconstitutional warrantless search_"
.
See United States v. Ravich,
. We observe that the Eleventh Circuit considers itself bound by decisions of the former Fifth Circuit, which would include
Navarro
and
Hanson. See Bonner
v.
City of Prichard,
.
See United States
v.
Pennington,
. As we have earlier pointed out, Rea and Elkins, though each invoked the Supreme Court’s supervisory power to exclude evidence, as distinct from the then understood principle that exclusion was compelled by or necessarily flowed from the Fourth Amendment itself, nevertheless were grounded on the unconstitutionality of the underlying search or seizure.
. The presence of these considerations is also reflected in the Court’s opinion in
Miranda v. Arizona,
. Nor do we consider the decisions in
Nardone v. United States,
The
Nardone
cases concerned a federal statute which made criminal the intercepting or divulging by anyone to "any person" of wire communications without consent of the sender. In
Nardone I,
the Court observed that “[t]o recite the contents of the message in testimony before a court is to divulge the message” and hence violate the statute.
Further, in the
Nardone
cases, the violation was not one of procedure but of substance, for there was no procedure available under which the communication could have lawfully been intercepted and divulged.
See Nardone I,
. Appellant also argues that here the federal officer relied on the state officers, not on the magistrate as such, while in Leon and Sheppard the reliance was directly on the magistrate. We do not dispute appellant’s reading of Leon and Sheppard, or the possible significance, in a Fourth Amendment context, of the distinction urged by appellant. We decline to give that distinction controlling significance here, largely for the same reasons we decline in the present context to require that the officers’ good faith be objectively reasonable. We also observe that in Williams we imposed no such requirement of reliance on a magistrate; and that while such reliance was present and expressly noted in Leon and Sheppard, neither opinion purports to address whether it is a general requirement of the objectively reasonable good faith test.
