Abel v. United States

362 U.S. 217, 80 S. Ct. 683, 4 L. Ed. 2d 668, 1960 U.S. LEXIS 1412

Opinions

Mr. Justice Frankfurter

delivered the opinion of the Court.

The question in this case is whether seven items were properly admitted into evidence at the petitioner’s trial for conspiracy to commit espionage. All seven items were seized by officers of the Government without a search warrant. The seizures did not occur in connection with the exertion of the criminal process against petitioner. They arose out of his administrative arrest by the United States Immigration and Naturalization Service as a preliminary to his deportation. A motion to suppress these items as evidence, duly made in the District Court, was denied after a full hearing. 155 F. Supp. 8. Petitioner was tried, convicted and sentenced to thirty years’ imprisonment and to the payment of a fine of $3,000. The Court of Appeals affirmed, 258 F. 2d 485. We granted certiorari, 358 U. S. 813, limiting the grant to the following two questions:

“1. Whether the Fourth and Fifth Amendments to the Constitution of the United States are violated by a search and the seizure of evidence without a search warrant, after an alien suspected and officially accused of espionage has been taken into custody for deportation, pursuant to an administrative Immigration Service warrant, but has not been arrested for the commission of a crime?

“2. Whether the Fourth and Fifth Amendments to the Constitution of the United States are violated when articles so seized are unrelated to the Immigration Service warrant and, together with other articles obtained from such leads, are introduced as evidence in a prosecution for espionage?”

Argument was first heard at October Term, 1958. The case having been set down for reargument at this Term, 359 U. S. 940, counsel were asked to discuss a series of additional questions, set out in the margin.*

We have considered the case on the assumption that the conviction must be reversed should we find challenged items of evidence to have been seized in violation of the Constitution and therefore improperly admitted into evidence. We find, however, that the admission of these items was free from any infirmity and we affirm the judgment. (Of course the nature of the case, the fact that it was a prosecution for espionage, has no bearing whatever upon the legal considerations relevant to the admissibility of evidence.)

The seven items, all in petitioner’s possession at the time of his administrative arrest, the admissibility of which is in question, were the following:

(1) a piece of graph paper, carrying groups of numbers arranged in rows, allegedly a coded message ;

(2) a forged birth certificate, certifying the birth of “Martin Collins” in New York County in 1897;

(3) a birth certificate, certifying the birth of “Emil Goldfus” in New York in 1902 (Emil Goldfus died in 1903) ;

(4) an international certificate of vaccination, issued in New York to “Martin Collins” in 1957;

(5) a bank book of the East River Savings Bank containing the account of “Emil Goldfus”;

(6) a hollowed-out pencil containing 18 microfilms; and

(7) a block of wood, wrapped in sandpaper, and containing within it a small booklet with a series of numbers on each page, a so-called “cipher pad.”

Items (2), (3), (4) and (5) were relevant to the issues of the indictment for which petitioner was on trial in that they corroborated petitioner’s use of false identities. Items (1), (6) and (7) were incriminatory as useful means for one engaged in espionage.

The main claims which petitioner pressed upon the Court may be thus summarized: (1) the administrative arrest was used by the Government in bad faith; (2) administrative arrests as preliminaries to deportation are unconstitutional; and (3) regardless of the validity of the administrative arrest here, the searches and seizures through which the challenged items came into the Government’s possession were not lawful ancillaries to such an arrest. These claims cannot be judged apart from the circumstances leading up to the arrest and the nature of the searches and seizures. It becomes necessary to relate these matters in considerable detail.

Petitioner was arrested by officers of the Immigration and Naturalization Service (hereafter abbreviated as I. N. S.) on June 21, 1957, in a single room in the Hotel Latham in New York City, his then abode. The attention of the I. N. S. had first been drawn to petitioner several days earlier when Noto, a Deputy Assistant Commissioner of the I. N. S., was told by a liaison officer of the Federal Bureau of Investigation (hereafter abbreviated as F. B. I.) that petitioner was believed by the F. B. I. to be an alien residing illegally in the United States. Noto was told of the F. B. I.’s interest in petitioner in connection with espionage.

An uncontested affidavit before the District Court asserted the following with regard to the events leading up to the F. B. I.’s communication with Noto about petitioner. About one month before the F. B. I. communicated with Noto, petitioner had been mentioned by Hay-hanen, a recently defected Russian spy, as one with whom Hayhanen had for several years cooperated in attempting to commit espionage. The F. B. I. had thereupon placed petitioner under investigation. At the time the F. B. I. communicated with the I. N. S. regarding petitioner, the case against him rested chiefly upon Hayhanen’s story, and Hayhanen, although he was later to be the Government’s principal witness at the trial, at that time insisted that he would refuse to testify should petitioner be brought to trial, although he would fully cooperate with the Government in secret. The Department of Justice concluded that without Hayhanen’s testimony the evidence was insufficient to justify petitioner’s arrest and indictment on espionage charges. The decision was thereupon made to bring petitioner to the attention of the I. N. S., with a view to commencing deportation proceedings against him.

Upon being notified of the F. B. I.’s belief that petitioner was residing illegally in this country, Noto asked the F. B. I. to supply the I. N. S. with further information regarding petitioner’s status as an alien. The F. B. I. did this within a week. The I. N. S. concluded that if petitioner were, as suspected, an alien, he would be subject to deportation in that he had failed to comply with the legal duty of aliens to notify the Attorney General every January of their address in the United States. 8 U. S. C. § 1305. Noto then determined on petitioner’s administrative arrest as a preliminary to his deportation. The F. B. I. was so informed. On June 20, two I. N. S. officers, Schoenenberger and Kanzler, were dispatched by Noto to New York to supervise the arrest. These officers carried with them a warrant for petitioner’s arrest and an order addressed to petitioner directing him to show cause why he should not be deported. They met in New York with the District Director of the I. N. S. who, after the information in the possession of the I. N. S. regarding petitioner was put before him, signed the warrant and the order. Following this, Schoenenberger and Kanzler went to F. B. I. headquarters in New York where, by prearrangement with the F. B. I. in Washington, they were met by several F. B. I. officers. These agreed to conduct agents of the I. N. S. to petitioner’s hotel so that the I. N. S. might accomplish his arrest. The F. B. I. officer in charge asked whether, before the petitioner was arrested, the F. B. I. might “interview” him in an attempt to persuade him to “cooperate” with regard to his espionage. To this Schoenenberger agreed.

At 7 o’clock the next morning, June 21, two officers of the I. N. S. and several F. B. I. men gathered in the corridor outside petitioner’s room at the Hotel Latham. All but two F. B. I. agents, Gamber and Blasco, went into the room next to petitioner’s, which the F. B. I. had occupied in the course of its investigation of petitioner. Gamber and Blasco were charged with confronting petitioner and soliciting his cooperation with the F. B. I. They had no warrant either to arrest or to search. If petitioner proved cooperative their instructions were to telephone to their superior for further instructions. If petitioner failed to cooperate they were to summon the waiting I. N. S. agents to execute their warrant for his arrest.

Gamber rapped on petitioner’s door. When petitioner released the catch, Gamber pushed open the door and walked into the room, followed by Blasco. The door was left ajar and a third F. B. I. agent came into the room a few minutes later. Petitioner, who was nude, was told to put on a pair of undershorts and to sit on the bed, which he did. The F. B. I. agents remained in the room questioning petitioner for about twenty minutes. Although petitioner answered some of their questions, he did not “cooperate” regarding his alleged espionage. A signal was thereupon given to the two agents of the I. N. S. waiting in the next room. These came/ into petitioner’s room and served petitioner with the warrant for his arrest and with the order to show cause. Shortly thereafter Schoenenberger and Kanzler, who had been waiting outside the hotel, also entered petitioner’s room. These four agents of the I. N. S. remained with petitioner in his room for about an hour. For part of this time an F. B. I. agent was also in the room and during all of it another F. B. I. agent stood outside the open door of the room, where he could observe the interior.

After placing petitioner under arrest, the four I. N. S. agents undertook a search of his person and of all of his belongings in the room, and the adjoining bathroom, which lasted for from fifteen to twenty minutes. Petitioner did not give consent to this search; his consent was not sought. The F. B. I. agents observed this search but took no part in it. It was Schoenenberger’s testimony to the District Court that the purpose of this search was to discover, weapons and documentary evidence of petitioner’s “alienage” — that is, documents to substantiate the information regarding petitioner’s status as an alien which the I. N. S. had received from the F. B. I. During this search one of the challenged items of evidence, the one we have designated (2), a birth certificate for “Martin Collins,” was seized. Weapons were not found, nor was any other evidence regarding petitioner’s “alienage.”

When the search was completed, petitioner was told to dress himself, to assemble his things and to choose what he wished to take with him. With the help of the I. N. S. agents almost everything in the room was packed into petitioner’s baggage. A few things petitioner deliberately left on a window sill, indicating that he did not want to take them, and several other things which he chose not to pack up into his luggage he put into the room’s wastepaper basket. When everything had been assembled, petitioner asked and received permission to repack one of his suitcases. While petitioner was doing so, Schoenenberger noticed him slipping some papers into the sleeve of his coat. Schoenenberger seized these. One of them was the challenged item of evidence which we have designated (1), a piece of graph paper containing a coded message.

When petitioner’s belongings had been completely packed, petitioner agreed to check out of the hotel. One of the F. B. I. agents obtained his bill from the hotel and petitioner paid it. Petitioner was then handcuffed and taken, along with his baggage, to a waiting automobile and thence to the headquarters of the I. N. S. in New York. At I. N. S. headquarters, the property petitioner had taken with him was searched more thoroughly than it had been in his hotel room, and three more of the challenged items were discovered and seized. These were the ones we have designated (3), (4) and (5), the “Emil Goldfus” birth certificate, the international vaccination certificate, and the bank book.

As soon as petitioner had been taken from the hotel, an F. B. I. agent, Kehoe, who had been in the room adjoining petitioner’s during the arrest and search and who, like the I. N. S. agents, had no search warrant, received permission from the hotel management to search the room just vacated by petitioner. Although the bill which petitioner had paid entitled him to occupy the room until 3 p. m. of that day, the hotel’s practice was to consider a room vacated whenever a guest removed his baggage and turned in his key. Kehoe conducted a search of petitioner’s room which lasted for about three hours. Among other things, he seized the contents of the wastepaper basket into which petitioner had put some things while packing his belongings. Two of the items thus seized were the challenged items of evidence we have designated (6) and (7): a hollow pencil containing microfilm and a block of wood containing a “cipher pad.”

Later in the day of his arrest, petitioner was taken by airplane to a detention center for aliens in Texas. He remained there for several weeks until arrested upon the charge of conspiracy to commit espionage for which he was brought to trial and convicted in the Eastern District of New York.

I.

The underlying basis of petitioner’s attack upon the admissibility of the challenged items of evidence concerns the motive of the Government in its use of the administrative arrest. We are asked to find that the Government resorted to a subterfuge, that the Immigration and Naturalization Service warrant here was a pretense and sham, was not what it purported to be. According to petitioner, it was not the Government’s true purpose in arresting him under this warrant to take him into custody pending a determination of his deportability. The Government’s real aims, the argument runs, were (1) to place petitioner in custody so that pressure might be brought to bear upon him to confess his espionage and cooperate with the P. B. I., and (2) to permit the Government to search through his belongings for evidence of his espionage to be used in a designed criminal prosecution against him. The claim is, in short, that the Government used this administrative warrant for entirely illegitimate purposes and that articles seized as a consequence of its use ought to have been suppressed.

Were this claim justified by the record, it would indeed reveal a serious misconduct by law-enforcing officers. The deliberate use by the Government of an administrative warrant for the purpose of gathering evidence in a criminal case must meet stern resistance by the courts. The preliminary stages of a criminal prosecution must be pursued in strict obedience to the safeguards and restrictions of the Constitution and laws of the United States. A finding of bad faith is, however, not open to us on this record. What the motive was of the I. N. S. officials who determined to arrest petitioner, and whether the I. N. S. in doing so was not exercising its powers in the lawful discharge of its own responsibilities but was serving as a tool for the F. B. I. in building a criminal prosecution against petitioner, were issues fully canvassed in both courts below. The crucial facts were found against the petitioner.

On this phase of the case the district judge, having permitted full scope to the elucidation of petitioner’s claim, having seen and heard witnesses, in addition to testimony by way of affidavits, and after extensive argument, made these findings:

“[T]he evidence is persuasive that the action taken by the officials of the Immigration and Naturalization Service is found to have been in entire good faith.

The testimony of Schoenenberger and Noto leaves no doubt that while the first information that came to them concerning the [petitioner] . . . was furnished by the F. B. I. — which cannot be an unusual happening — the proceedings taken by the Department differed in no respect from what would have been done in the case of an individual concerning whom no such information was known to exist.

“The defendant argues that the testimony establishes that the arrest was made under the direction and supervision of the F. B. I., but the evidence is to the contrary, and it is so found.

“No good reason has been suggested why these two branches of the Department of Justice should not cooperate, and that is the extent of the showing made on the part of the defendant.” 155 F. Supp. 8, 11.

The opinion of the Court of Appeals, after careful consideration of the matter, held that the answer “must clearly be in the affirmative” to the question “whether the evidence in the record supports the finding of good faith made by the court below.” 258 F. 2d 485, 494.

Among the statements in evidence relied upon by the lower courts in making these findings was testimony by Noto that the interest of the I. N. S. in petitioner was confined to petitioner’s illegal status in the United States; that in informing the I. N. S. about petitioner’s presence in the United States the F. B. I. did not indicate what action it wanted the I. N. S. to take; that Noto himself made the decision to arrest petitioner and to commence deportation proceedings against him; that the F. B. I. made no request of him to search for evidence of espionage at the time of the arrest; and that it was “usual and mandatory” for the F. B. I. and I. N. S. to work together in the manner they did. There was also the testimony of Schoenenberger, regarding the purpose of the search he made of petitioner’s belongings, that the motive was to look for weapons and documentary evidence of alienage. To be sure, the record is not barren of evidence supporting an inference opposed to the conclusion to which the two lower courts were led by the record as a whole: for example, the facts, that the I. N. S. held off its arrest of petitioner while the F. B. I. solicited his cooperation, and that the F. B. I. held itself ready to search petitioner’s room as soon as it was vacated. These elements, however, did not, and were not required to, persuade the two courts below in the face of ample evidence of good faith to the contrary, especially the human evidence of those involved in the episode. We are not free to overturn the conclusion of the courts below when justified by such solid proof.

Petitioner’s basic contention comes down to this: even without a showing of bad faith, the F. B. I. and I. N. S. must be held to have cooperated to an impermissible extent in this case, the case being one where the alien arrested by the I. N. S. for deportation was also suspected by the F. B. I. of crime. At the worst, it may be said that the circumstances of this case reveal an opportunity for abuse of the administrative arrest. But to hold illegitimate, in the absence of bad faith, the cooperation between I. N. S. and F. B. I. would be to ignore the scope of rightful cooperation between two branches of a single Department of Justice concerned with enforcement of different areas of law under the common authority of the Attorney General.

The facts are that the F. B. I. suspected petitioner both of espionage and illegal residence in the United States as an alien. That agency surely acted not only with propriety but in discharge of its duty in bringing petitioner’s illegal status to the attention of the I. N. S., particularly after it found itself unable to proceed with petitioner’s prosecution for espionage. Only the I. N. S. is authorized to initiate deportation proceedings, and certainly the F. B. I. is not to be required to remain mute regarding one they have reason to believe to be a deportable alien, merely because he is also suspected of one of the gravest of crimes and the F. B. I. entertains the hope that criminal proceedings may eventually be brought against him. The I. N. S., just as certainly, would not have performed its responsibilities had it been deterred from instituting deportation proceedings solely because it became aware of petitioner through the F. B. I., and had knowledge that the F. B. I. suspected petitioner of espionage. The Government has available two ways of dealing with a criminally suspect deportable alien. It would make no sense to say that branches of the Department of Justice may not cooperate in pursuing one course of action or the other, once it is honestly decided what course is to be preferred. For the same reasons this cooperation may properly extend to the extent and in the manner in which the F. B. I. and I. N. S. cooperated in effecting petitioner’s administrative arrest. Nor does it taint the administrative arrest that the F. B. I. solicited petitioner’s cooperation before it took place, stood by while it did, and searched the vacated room after the arrest. The F. B. I. was not barred from continuing its investigation in the hope that it might result in a prosecution for espionage because the I. N. S., in the discharge of its duties, had embarked upon an independent decision to initiate proceedings for deportation.

The Constitution does not require that honest law enforcement should be put to such an irrevocable choice between two recourses of the Government. For a contrast to the proper cooperation between two branches of a single Department of Justice as revealed in this case, see the story told in Colyer v. Skeffington, 265 F. 17. That case sets forth in detail the improper use of immigration authorities by the Bureau of Investigation of the Department of Justice when the immigration service was a branch of the Department of Labor and was acting not within its lawful authority but as the cat’s paw of another, unrelated branch of the Government.

We emphasize again that our view of the matter would be totally different had the evidence established, or were the courts below not justified in not finding, that the administrative warrant was here employed as an instrument of criminal law enforcement to circumvent the latter’s legal restrictions, rather than as a bona fide preliminary step in a deportation proceeding. The test is whether the decision to proceed administratively toward deportation was influenced by, and was carried out for, a purpose of amassing evidence in the prosecution for crime. The record precludes such a finding by this Court.

II.

The claim that the administrative warrant by which petitioner was arrested was invalid, because it did not satisfy the requirements for “warrants” under the Fourth Amendment, is not entitled to our consideration in the circumstances before us. It was not made below; indeed, it was expressly disavowed. Statutes authorizing administrative arrest to achieve detention pending deportation proceedings have the sanction of time. It would emphasize the disregard for the presumptive respect the Court owes to the validity of Acts of Congress, especially when confirmed by uncontested historical legitimacy, to bring into question for the first time such a long-sanctioned practice of government at the behest of a party who not only did not challenge the exercise of authority below, but expressly acknowledged its validity.

The grounds relied on in the trial court and the Court of Appeals by petitioner were solely (in addition to the insufficiency of the evidence, a contention not here for review) (1) the bad faith of the Government’s use of the administrative arrest warrant and (2) the lack of a power incidental to the execution of an administrative warrant to search and seize articles for use as evidence in a later criminal prosecution. At no time did petitioner question the legality of the administrative arrest procedure either as unauthorized or as unconstitutional. Such challenges were, to repeat, disclaimed. At the hearing on the motion to suppress, petitioner’s counsel was questioned by the court regarding the theory of relief relied upon:

“The Court: They [the Government] were not at liberty to arrest him [petitioner] ?

“Mr. Fraiman: No, your Honor.

“They were perfectly proper in arresting him.

“We don’t contend that at all.

“As a matter of fact, we contend it was their duty to arrest this man as they did.

“I think it should show or rather, it showed admirable thinking on the part of the F. B. I. and the Immigration Service.

“We don’t find any fault with that.

“Our contention is that although they were permitted to arrest this man, and in fact, had a duty to arrest this man in a manner in which they did, they did not have a right to search his premises for the material which related to espionage.

“. . . He was charged with no criminal offense in this warrant.

“The Court: He was suspected of being illegally in the country, wasn’t he?

“Mr. Fraiman: Yes, your Honor.

“The Court: He was properly arrested.

“Mr. Fraiman: He was properly arrested, we concede that, your Honor.”

Counsel further made it plain that the arrest warrant whose validity he was conceding was “one of these Immigration warrants which is obtained without any background material at all.” Affirmative acceptance of what is now sought to be questioned could not be plainer.

The present form of the legislation giving authority to the Attorney General or his delegate to arrest aliens pending deportation proceedings under an administrative warrant, not a judicial warrant within the scope of the Fourth Amendment, is § 242 (a) of the Immigration and Nationality Act of 1952. (8 U. S. C. § 1252 (a)). The regulations under this Act delegate the authority to issue these administrative warrants to the District Directors of the I. N. S. “[a]t the commencement of any proceeding [to deport] ... or at any time thereafter . . . whenever, in [their] . . . discretion, it appears that the arrest of the respondent is necessary or desirable.” 8 CFR § 242.2 (a). Also, according to these regulations, proceedings to deport are commenced by orders to show cause issued by the District Directors or others; and the “Operating Instructions” of the I. N. S. direct that the application for an order to show cause should be based upon a showing of a prima facie case of deportability. The warrant of arrest for petitioner was issued by the New York District Director of the I. N. S. at the same time as he signed an order to show cause. Schoenenberger testified that, before the warrant and order were issued, he and Kanzler related to the District Director what they had learned from the F. B. I. regarding petitioner’s status as an alien, and the order to show cause recited that petitioner had failed to register, as aliens must. Since petitioner was a suspected spy, who had never acknowledged his residence in the United States to the Government or openly admitted his presence here, there was ample reason to believe that his arrest pending deportation was “necessary or desirable.” The arrest procedure followed in the present case fully complied with the statute and regulations.

Statutes providing for deportation have ordinarily authorized the arrest of deportable aliens by order of an executive official. The first of these was in 1798. Act of June 25, 1798, c. 58, § 2, 1 Stat. 571. And see, since that time, and before the present Act, Act of Oct. 19, 1888, c. 1210, 25 Stat. 566; Act of Mar. 3, 1903, c. 1012, § 21, 32 Stat. 1218; Act of Feb. 20, 1907, c. 1134, § 20, 34 Stat. 904; Act of Feb. 5, 1917, c. 29, § 19, 39 Stat. 889; Act of Oct. 16, 1918, c. 186, § 2, 40 Stat. 1012; Act of May 10, 1920, c. 174, 41 Stat. 593; Internal Security Act of 1950, c. 1024, Title I, § 22, 64 Stat. 1008. To be sure, some of these statutes, namely the Acts of 1888, 1903 and 1907, dealt only with aliens who had landed illegally in the United States, and not with aliens sought to be deported by reason of some act or failure to act since entering. Even apart from these, there remains overwhelming historical legislative recognition of the propriety of administrative arrest for deportable aliens such as petitioner.

The constitutional validity of this long-standing administrative arrest procedure in deportation cases has never been directly challenged in reported litigation. Two lower court cases involved oblique challenges, which were summarily rejected. Podolski v. Baird, 94 F. Supp. 294; Ex parte Avakian, 188 F. 688, 692. See also the discussion in Colyer v. Skeffington, 265 F. 17, reversed on other grounds sub nom. Skeffington v. Katzeff, 277 F. 129, where the District Court made an exhaustive examination of the fairness of a group of deportation proceedings initiated by administrative arrests, but nowhere brought into question the validity of the administrative arrest procedure as such. This Court seems never expressly to have directed its attention to the particular question of the constitutional validity of administrative deportation warrants. It has frequently, however, upheld administrative deportation proceedings shown by the Court’s opinion to have been begun by arrests pursuant to such warrants. See The Japanese Immigrant Case, 189 U. S. 86; Zakonaite v. Wolf, 226 U. S. 272; Bilokumsky v. Tod, 263 U. S. 149; Carlson v. Landon, 342 U. S. 524. In Carlson v. Landon, the validity of the arrest was necessarily implicated, for the Court there sustained discretion in the Attorney General to deny bail to alien Communists held pending deportation on administrative arrest warrants. In the presence of this impressive historical evidence of acceptance of the validity of statutes providing for administrative deportation arrest from almost the beginning of the Nation, petitioner’s disavowal of the issue below calls for no further consideration.

III.

Since.petitioner’s arrest was valid, we reach the question whether the seven challenged items, all seized during searches which were a direct consequence of that arrest, were properly admitted into evidence. This issue raises three questions: (1) Were the searches which produced these items proper searches for the Government to have made? If they were not, then whatever the nature of the seized articles, and however proper it would have been to seize them during a valid search, they should have been suppressed as the fruits of activity in violation of the Fourth Amendment. E. g., Weeks v. United States, 232 U. S. 383, 393. (2) Were the articles seized properly subject to seizure, even during a lawful search? We have held in this regard that not every item may be seized which is properly inspectible by the Government in the course of a legal search; for example, private papers desired by the Government merely for use as evidence may not be seized, no matter how lawful the search which discovers them, Gouled v. United States, 255 U. S. 298, 310, nor may the Government seize, wholesale, the contents of a house it might have searched, Kremen v. United States, 353 U. S. 346. (3) Was the Government free to use the articles, even if properly seized, as evidence in a criminal case, the seizures having been made in the course of a separate administrative proceeding?

The most fundamental of the issues involved concerns the legality of the search and seizures made in petitioner’s room in the Hotel Latham. The ground of objection is that a search may not be conducted as an incident to a lawful administrative arrest.

We take as a starting point the cases in this Court dealing with the extent of the search which may properly be made without a warrant following a lawful arrest for crime. The several cases on this subject in this Court cannot be satisfactorily reconciled. This problem has, as is well-known, provoked strong and fluctuating differences of view on the Court. This is not the occasion to attempt to reconcile all the decisions, or to re-examine them. Compare Marron v. United States, 275 U. S. 192, with Go-Bart Co. v. United States, 282 U. S. 344, and United States v. Lejkowitz, 285 U. S. 452; compare Go-Bart, supra, and Lejkowitz, supra, with Harris v. United States, 331 U. S. 145, and United States v. Rabinowitz, 339 U. S. 56; compare also Harris, supra, with Trupiano v. United States, 334 U. S. 699, and Trupiano with Rabinowitz, supra (overruling Trupiano). Of these cases, Harris and Rabinowitz set by far the most permissive limits upon searches incidental to lawful arrests. In view of their judicial context, the trial judge and the Government justifiably relied upon these cases for guidance at the trial; and the petitioner himself accepted the Harris case on the motion to suppress, nor does he ask this Court to reconsider Harris and Rabinowitz. It would, under these circumstances, be unjustifiable retro spective lawmaking for the Court in this case to reject the authority of these decisions.

Are there to be permitted incidental to valid administrative arrests, searches as broad in physical area as, and analogous in purpose to, those permitted by the applicable precedents as incidents to lawful arrests for crime? Specifically, were the officers of the I. N. S. acting lawfully in this case when, after his arrest, they searched through petitioner’s belongings in his hotel room looking for weapons and documents to evidence his “alienage”? There can be no doubt that a search for weapons has as much justification here as it has in the case of an arrest for crime, where it has been recognized as proper. E. g., Agnello v. United States, 269 U. S. 20, 30. It is no less important for government officers, acting under established procedure to effect a deportation arrest rather than one for crime, to protect themselves and to insure that their prisoner retains no means by which to accomplish an escape.

Nor is there any constitutional reason to limit the search for materials proving the deportability of an alien, when validly arrested, more severely than we limit the search for materials probative of crime when a valid criminal arrest is made. The need for the proof is as great in one case as in the other, for deportation can be accomplished only after a hearing at which deportability is established. Since a deportation arrest warrant is not a judicial warrant, a search incidental to a deportation arrest is without the authority of a judge or commissioner. But so is a search incidental to a criminal arrest made upon probable cause without a warrant, and under Rabinowitz, 339 U. S., at 60, such a search does not require a judicial warrant for its validity. It is to be remembered that an I. N. S. officer may not arrest and search on his own. Application for a warrant must be made to an independent responsible officer, the District Director of the I. N. S., to whom a prima facie case of deportability must be shown. The differences between the procedural protections governing criminal and deportation arrests are not of a quality or magnitude to warrant the deduction of a constitutional difference regarding the right of incidental search. If anything, we ought to be more vigilant, not less, to protect individuals and their property from warrantless searches made for the purpose of turning up proof to convict than we are to protect them from searches for matter bearing on deportability. According to the uniform decisions of this Court deportation proceedings are not subject to the constitutional safeguards' for criminal prosecutions. Searches for evidence of crime present situations demanding the greatest, not the least, restraint upon the Government’s intrusion into privacy; although its protection is not limited to them, it was at these searches which the Fourth Amendment was primarily directed. We conclude, therefore, that government officers who effect a deportation arrest have a right of incidental search analogous to the search permitted criminal law-enforcement officers.

Judged by the prevailing doctrine, the search of petitioner’s hotel room was justified. Its physical scope, being confined to the petitioner’s room and the adjoining bathroom,' was far less extensive than the search in Harris. The search here was less intensive than were the deliberately exhaustive quests in Harris and Rabino-witz, and its purpose not less justifiable. The only things sought here, in addition to weapons, were documents connected with petitioner’s status as an alien. These may well be considered as instruments or means for accomplishing his illegal status, and thus proper objects of search under Harris, supra, 331 U. S., at 154.

Two of the challenged items were seized during this search of petitioner’s property at his hotel room. The first was item (2), a forged New York birth certificate for “Martin Collins,” one of the false identities which petitioner assumed in this country in order to keep his presence here undetected. This item was seizable when found during a proper search, not only as a forged official document by which petitioner sought to evade his obligation to register as an alien, but also as a document which petitioner was using as an aid in the commission of espionage, for his undetected presence in this country was vital to his work as a spy. Documents used as a means to commit crime are the proper subjects of search warrants, Gouled v. United States, 255 U. S. 298, and are seizable when discovered in the course of a lawful search, Marron v. United States, 275 U. S. 192.

The other item seized in the course of the search of petitioner’s hotel room was item (1), a piece of graph paper containing a coded message. This was seized by Schoenenberger as petitioner, while packing his suitcase, was seeking to hide it in his sleeve. An arresting officer is free to take hold of articles which he sees the accused deliberately trying to hide. This power derives from the dangers that a weapon will be concealed, or that relevant evidence will be destroyed. Once this piece of graph paper came into Schoenenberger’s hands, it was not necessary for him to return it, as it was an instrumentality for the commission of espionage. This is so even though Schoen-enberger was not only not looking for items connected with espionage but could not properly have been searching for the purpose of finding such items. When an article subject to lawful seizure properly comes into an officer’s possession in the course of a lawful search it would be entirely without reason to say that he must return it because it was not one of the things it was his business to look for. See Harris, supra, 331 U. S., at 154-155.

Items (3), (4), and (5), a birth certificate for “Emil Goldfus” who died in 1903, a certificate of vaccination for “Martin Collins,” and a bank book for “Emil Goldfus” were seized, not in petitioner’s hotel room, but in a more careful search at I. N. S. headquarters of the belongings petitioner chose to take with him when arrested. This search was a proper one. The property taken by petitioner to I. N. S. headquarters was all property which, under Harris, was subject to search at the place of arrest. We do not think it significantly different, when the accused decides to take the property with him, for the search of it to occur instead at the first place of detention when the accused arrives there, especially as the search of property carried by an accused to the place of detention has additional justifications, similar to those which justify a search of the person of one who is arrested. It is to be noted that this is not a case, like Kremen v. United States, 353 U. S. 346, where the entire contents of the place where the arrest was made were seized. Such a mass seizure is illegal. The Government here did not seize the contents of petitioner’s hotel room. Petitioner took with him only what he wished. He chose to leave some things behind in his room, which he voluntarily relinquished. And items (3), (4), and (5) were articles subject to seizure when found during a lawful search. They were all capable of being used to establish and maintain a false identity for petitioner, just as the forged “Martin Collins” birth certificate, and were seizable for the same reasons.

Items (l)-(5) having come into the Government’s possession through lawful searches and seizures connected with an arrest pending deportation, was the Government free to use them as evidence in a criminal prosecution to which they related? We hold that it was. Good reason must be shown for prohibiting the Government from using relevant, otherwise admissible, evidence. There is excellent reason for disallowing its use in the case of evidence, though relevant, which is seized by the Government in violation of the Fourth Amendment to the Constitution. “If letters and private documents can thus 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.” Weeks v. United States, 232 U. S. 383, 393.

These considerations are here absent, since items (l)-(5) were seized as a consequence of wholly lawful conduct. That being so, we can see no rational basis for excluding these relevant items from trial: no wrongdoing police officer would thereby be indirectly condemned, for there were no such wrongdoers; the Fourth Amendment would not thereby be enforced, for no illegal search or seizure was made; the Court would be lending its aid to no lawless government action, for none occurred. Of course cooperation between the branch of the Department of Justice dealing with criminal law enforcement and the branch dealing with the immigration laws would be less effective if evidence lawfully seized by the one could not be used by the other. Only to the extent that it would be to the public interest to deter and prevent such cooperation, would an exclusionary rule in a case like the present be desirable. Surely no consideration of civil liberties commends discouragement of such cooperation between these two branches when undertaken in good faith. When undertaken in bad faith to avoid constitutional restraints upon criminal law enforcement the evidence must be suppressed. That is not, as we have seen, this case. Individual cases of bad faith cooperation should be dealt with by findings to that effect in the cases as they arise, not by an exclusionary rule preventing effective cooperation when undertaken in entirely good faith.

We have left to the last the admissibility of items (6) and (7), the hollowed-out pencil and the block of wood containing a “cipher pad,” because their admissibility is founded upon an entirely different set of considerations. These two items were found by an agent of the F. B. I. in the course of a search he undertook of petitioner’s hotel room, immediately after petitioner had paid his bill and vacated the room. They were found in the room’s wastepaper basket, where petitioner had put them while packing his belongings and preparing to leave. No pretense is made that this search by the F. B. I. was for any purpose other than to gather evidence of crime, that is, evidence of petitioner’s espionage. As such, however, it was entirely lawful, although undertaken without a warrant. This is so for the reason that at the time of the search petitioner had vacated the room. The hotel then had the exclusive right to its possession, and the hotel management freely gave its consent that the search be made. Nor was it unlawful to seize the entire contents of the wastepaper basket, even though some of its contents had no connection with crime. So far as the record shows, petitioner had'abandoned these articles. He had thrown them away. So far as he was concerned, they were bona vacantia. There can be nothing unlawful in the Government’s appropriation of such abandoned property. See Hester v. United States, 265 U. S. 57, 58. The two items which were eventually introduced in evidence were assertedly means for the commission of espionage, and were themselves seizable as such. These two items having been lawfully seized by the Government in connection with an investigation of crime, we encounter no basis for discussing further their admissibility as evidence.

Affirmed.
