OPINION OF THE COURT
Before GANEY, ADAMS, Circuit Judges, and WEIS, District Judge.
This appeal from the denial of a petition for a writ of habeas corpus raises a difficult and vexing problem in interpreting the Fourth Amendment’s prohibition against unreasonable searches and seizures. 1 Judge Sorg, of the District Court for the Western District of Pennsylvania, denied Brown’s petition, and we affirm.
After a trial by jury, Brown was convicted of second degree murder and sentenced to a term of ten to twenty years at the State Correctional Institution, Pittsburgh, Pennsylvania. The single question raised by Brown in his appeal to the Pennsylvania Supreme Court and now presented to this Court is whether application of the Fourth Amendment’s prohibition against unreasonable searches and seizures requires that a revolver given to the police by Brown should have been suppressed and not admitted as evidence against Brown during his murder trial.
The facts are undisputed and both sides rely upon the summary set forth in the opinion of the Pennsylvania Supreme Court, Commonwealth v. Brown,
*956
Brown contends that the revolver, its holster, and bullets were improperly admitted into evidence at his trial, because the Fourth Amendment prohibits the police from obtaining evidence through deceit and misrepresentation, and that the deceit and misrepresentation in this case is the undisclosed intention on the part of Petrovitch to have the ballistics test performed. Brown relies upon Gouled v. United States,
In
Gouled,
the Intelligence Department of the United States Army had investigated the defendant, because he was suspected of being a party to a conspiracy “to defraud the government through contracts with it for clothing and equipment.” Pursuant to the Investigation a Private Cohen, following the orders of officers within Army Intelligence, “pretending to make a friendly call upon the defendant, gained admission to his office and, in [Gouled’s] absence, without warrant of any character, seized and carried away several documents” which were subsequently admitted into evidence against Gouled.
Brown refers, also, to two district court decisions as authority for the proposition that the introduction into evidence of the revolver violated the Fourth Amendment: United States v. Lipshitz,
Likewise,
Ong Goon Sing
does not establish a rule of law applicable to the facts presently before this Court, because in
Ong Goon Sing
the basis for the decision of the District Court was that “[U]nder the circumstances of movant’s inability to understand English and the ‘request’ of the Special Agent and Investigator that he accompany them forthwith to the United States Attorney’s office and in lieu thereof follow their written instructions to come there a week later, the obtainment by the government of all the papers was not with the movant’s unequivocal and specific consent, freely and intelligently given without moral compulsion.”
Hence, as in Gouled both district court cases contain findings of Fourth Amendment violations predicated upon factual determination that the police had seized evidence without the voluntary consent of the defendants. Thus, neither Gouled, Lipshitz, nor Ong Goon. Sing control this case, since Brown does not contend that the alleged unreasonableness of this particular search resulted from the absence of his voluntary consent. 4 Rather, Brown argues that the search became unreasonable when his consent was procured through the police officers’ guile and misrepresentation. However, since nothing in the record reveals coercion, and Brown does not make such an allegation, we think the method by which Petrovitch obtained possession of the revolver was permissible within the meaning of the Fourth Amendment. The most likely explanation for Brown’s ingenuous actions is that he hoped to dissipate the suspicions of the police officers. Whether an attempt to lead the police astray in their investigation, or the act *958 of a gullible and inept criminal, Brown’s uncoerced relinquishment of the gun did not constitute an unreasonable search and seizure.
To hold, as Brown urges, that the revolver must be suppressed under the circumstances of this case would be a long step toward outlawing all undercover police investigations. If the police must announce their investigatory intentions even when acting openly in their official capacities, it might well follow that the police also must explain their purposes to criminal suspects when carrying out undercover investigations in which it is necessary that the police camouflage their identity. Clearly, the quantum of “guile and deceit” is greater when the police assume disguises to penetrate illegal enterprises than when the police acknowledge their official identity, but conceal some, if not all, of their intentions.
Indeed, a line of Supreme Court cases has established that it is constitutionally permissible for the police to conduct criminal investigations without revealing their official status and their clandestine purposes: Lewis v. United States,
In
Lopez
an Internal Revenue Agent secretly recorded the defendant’s bribery attempt. The defendant contended that “in view of Davis’ alleged falsification of his mission, he gained access to petitioner’s office by misrepresentation and all evidence obtained in the office,
i. e.,
his conversation with petitioner, was illegally ‘seized.’ ” The Court decided that the record of the conversation did not violate the Fourth Amendment.
In Lewis v. United States,
supra,
the Supreme Court considered a claim of error similar to that which was earlier raised in
Lopez.
It was argued in
Lewis
“that, in the absence of a warrant, any official intrusion upon the privacy of a home constitutes a Fourth Amendment violation and that the fact the suspect invited the intrusion cannot be held a waiver when the invitation was induced by fraud and deception.”
The holding in Hoffa v. United States,
supra,
is in accord with
Lopez
and
Lewis.
There the Court stated that a government informer need not reveal his se
*959
cret purpose before constitutionally seizing evidence obtained as a result of the defendant’s misplaced confidence. Because Brown voluntarily relinquished the murder weapon and authorized its sale, under the facts of this ease we think the subsequent performance of a ballistics test did not constitute an unreasonable search. That Brown realized his error by the time of trial does not require the courts to stretch the meaning of the Fourth Amendment so as to insulate Brown from the consequences of his voluntary surrender of the hand-gun. We are aware of no case holding that the Fourth Amendment prohibits reasonable, but also cunning, police work. Indeed, the recent decision of the Supreme Court in Procunier v. Atchley,
We are attentive to the thrust of Justice Stewart’s opinion in Katz v. United States,
Under the circumstances here, when Brown authorized the sale of the revolver he voluntarily abandoned the shield provided by the Fourth Amendment — both under traditional concepts of the law of property and under the emerging right to personal privacy.
Accordingly, the order of the District Court will be affirmed.
Notes
. Since this case presents a serious constitutional question, we feel compelled to comment on the fact that counsel has been less than helpful, having filed a “brief” which contained only a one-half page statement of facts and no argument. The fact that petitioner Brown filed a brief pro se, does not relieve counsel of his responsibilities to aid this Court in reaching a correct decision.
. The Supreme Court of Pennsylvania in Commonwealth v. Brown, supra, in scholarly and thoughtful opinions, Justice Cohen, speaking for the majority and Justice Roberts dissenting, considered the issue raised by petitioner Brown in this Habeas Corpus proceeding. Because of the importance of the constitutional claims raised by Brown, we find it necessary to express our reasons for affirming tbe denial of Brown’s petition.
. It is unclear whether the police ever entered Brown’s apartment. When Brown was at first questioned by the police, at Brown’s request the interview took place in a police car parked in front of his apartment house.
. There is a meaningful difference between seizing a citizen’s private papers or information contained therein without permission, as was the circumstances of Gouled, Livshits and Ong Goon Sing, and obtaining possession of a revolver with the owner’s consent but while harboring a concealed investigatory intent, as was accomplished in Brown’s case.
