¶11The government appeals from a pretrial order suppressing the fruits of two searches, a warrantless search of three suitcases outside the entrance to the Miami International Airport and a search under warrant of a house. Presumably the government bases its right to appeal on § 14 of Title III of the Omnibus Crime Control Act of 1970, 18 U.S.C. § 3731. We have considerable doubt whether we should review' the order, but we do so with the aim that our caveat below1 may give some guidance for future cases, and without any commitment on our part to review future pretrial suppression orders in a like posture. We conclude that the District Court correctly found the searches of the suitcases to be illegal but that it erred in suppressing fruits of the house search.
¶12On December 17, 1971, federal narcotics agents received word from Sarah Cook that persons whom she knew as Freddie, Rafael, and Argentine were expecting a large shipment of narcotics. Cook previously had been a reliable informant to the FBI, and that agency had put her in touch with narcotics agents concerning this particular information. About 2:00 p. m. on January 4, 1972, Cook reported to a narcotics agent that she had been to the house of defendant Ana Rose Betancourt, had asked Betancourt whether the narcotics were in, and Betancourt had said “the stuff was in.” Cook related that on this occasion she saw defendants Alfredo Aviles (“Alfredo”) and Marta Sierra in Betan-court’s house.
¶13Agents promptly placed the Betan-court residence under surveillance, and at approximately 4:00 p. m. of the same day they observed Alfredo and Sierra leave the house carrying a brown trash bag, enter a car, and place the bag on the seat. Alfredo drove the car a few blocks away to a point where Sierra deposited the bag in a trash receptacle. An agent retrieved it. Inside were clear plastic bags and torn Christmas wrapping paper, each containing traces of a white powder which, on field test, was disclosed to contain an opium derivative. Later in the afternoon Cook told agents she had just left the Betancourt residence; that inside were Betancourt, Sierra, Angel Aviles (“Angel”), Rafael Soriano, and Edward Arroyo; that she had seen suitcases and Christmas packages there; and that the parties had been whispering to each other.
¶14*472The agents continued their surveillance of the Betancourt residence. At 10:00 p. m. on January 4 they observed defendants Angel, Domingo Colon,' and Soriano exit the Betancourt residence carrying three large suitcases. They entered a taxicab which agents followed to the entrance of the Miami International Airport. Acting without a warrant, the agents stopped the cab on the ramp outside the Airport entrance, arrested the passengers, opened the cab’s trunk, and removed the suitcases. After the cab and the arrestees had been removed from the ramp the agents opened the suitcases, searched them, and seized plastic bags of white powder that are in part the subject of the pretrial motion to suppress.
¶15Meanwhile other agents had been preparing affidavits and securing a .warrant pursuant to which they planned to search the Betancourt residence. Between 11:00 and 11:30 p. m. an agent appeared before a magistrate who signed the search warrant, and the house was searched when an officer arrived with the warrant. The search produced evidence that defendants seek to suppress.
¶161. The suitcase search
¶17The agents had probable cause to believe that the occupants of the taxicab were carrying narcotics in their suitcases, and appellees do not seriously contend otherwise. The agents were justified in opening the trunk and removing the suitcases under Chambers v. Maroney, 399 U.S. 42, 90 S.Ct. 1975, 26 L.Ed.2d 419 (1970), and its progeny in this circuit.2 The intrusion into the cab’s trunk met the criteria for warrant-less vehicular searches set out in Coolidge v. New Hampshire, 403 U.S. 443, 460, 91 S.Ct. 2022, 29 L.Ed.2d 564, 579 (1971). Under the circumstances the officers could legitimately seize these suitcases — they were not required to leave them in the cab or on the sidewalk to be taken away or to disappear. War-rantless temporary detentions of containers that officials have probable cause to believe contain contraband, such as parcels in transit, have been approved by the Supreme Court when demanded by the exigencies of the situation. See, e. g., United States v. Van Leeuwen, 397 U.S. 249, 90 S.Ct. 1029, 25 L.Ed.2d 282 (1970). The crucial question before us is whether the agents, having seized the suitcases, could open and search them of whether, while retaining them in their dominion and control, they were required to appear before a magistrate and seek a warrant to examine them.
¶18Indubitably the suitcases were “effects” within the fourth amendment’s protection of “[t]he right of the people to be secure in their persons, houses, papers, and effects.” To justify a warrantless search the government must fit it within an established exception. “[S]earches conducted outside the judicial process, without prior approval by judge or magistrate, are per se unreasonable under the Fourth Amendment— subject only to a few specifically established and well-delineated exceptions,” and “the burden is on those seeking the exemption to show the need for it.” Coolidge v. New Hampshire, supra,403 U.S. at 454-455, 91 S.Ct. at 2030, 29 L. Ed.2d at 576.3 As Justice Jackson ex*473plained in Johnson v. United States, 333 U.S. 10, 68 S.Ct. 367, 92 L.Ed. 436 (1948), with characteristic clarity:
The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime. . . . When the right of privacy must yield to the right of search is, as a rule, to be decided by a judicial officer, not by a policeman or Government enforcement agent.
¶19Id. at 13-14, 68 S.Ct. at 369, 92 L.Ed. at 440. We must therefore analyze the reasons advanced by the government toward fulfilling its burden and determine if the warrantless search of the suitcases fits within one of the well-defined exceptions to the fourth amendment’s warrant requirement.
¶20 At the threshold we put aside as inapplicable several theories sometimes advanced to justify warrantless searches of such personal effects as handbags, suitcases, billfolds, or briefcases. The government does not argue that the search was legitimately incident to a lawful arrest under Chimel v. California, 395 U.S. 752, 89 S.Ct. 2034, 23 L.Ed.2d 685 (1969).4 Nor does the government claim that the search was valid under the plain view doctrine 5 or under the theory of abandonment,6 and, appro*474priately, there is no suggestion that constitutional analysis should vary because by hindsight we know the agents discovered contraband.7 Instead the government stakes its case on two principal arguments: (1) exigent circumstances justified failure to secure a warrant; and (2) a warrant to search personal effects is not required after they have been legitimately seized.7A
¶21a. Exigent circumstances
¶22 Exigent circumstances requiring an immediate search may operate in some cases to excuse time-consuming resort to judicial processes for issuance of a warrant. E. g., Terry v. Ohio, 392 U.S. 1, 20, 88 S.Ct. 1868, 20 L.Ed.2d 889, 905 (1968); McDonald v. United States, 335 U.S. 451, 455-456, 69 S.Ct. 191, 93 L.Ed. 153, 158 (1948). The only exigent circumstance advanced by the government in this case is that opening the suitcases immediately might have disclosed information which possibly would have led to the capture of others participating in the narcotics operation.7B This does not stand constitutional scrutiny.8 The argument proves too much. If this court were to accept as legitimate the government’s loosely defined concept of exigent circumstances, scarcely a case would remain in which a warrantless search for narcotics would not be justified. There is almost always a chance that newly discovered evidence will ensnare unknown accomplices. Also, a magistrate was readily available in the Miami area — one was contemporaneously signing a warrant to search the Betancourt residence — so the officers would have lost little time in detaining the suitcases until a warrant was secured.9 Additionally, so far as the record discloses, none of the officers even entertained a notion that a temporary delay in searching the suitcases would have in any manner prejudiced their planned raid on the Betancourt residence. And, finally, the agents ac*475knowledged what in good sense we all know — their purpose- in searching the suitcases was to confirm that they contained the narcotics which the agents suspected they contained. Compare Sibron v. New York, 392 U.S. 40, 88 S.Ct. 1889, 20 L.Ed.2d 917 (1968).
¶23b. Post-seizure search theory
¶24As previously pointed out, the officers would have acted within the fourth amendment by seizing and detaining the suitcases pending a request to judicial authority for a search warrant. The government theorizes that the justifiable seizure authorized an immediate, war-rantless, on-the-scene opening and search of the suitcases. This theory is built on language in Chambers v. Maro-ney, supra, an automobile search case, in which the Supreme Court intimated that there was no constitutional difference “between on the one hand seizing and holding a car before presenting the probable cause issue to a magistrate and on the other hand carrying out an immediate search without a warrant.” 10 We are in fundamental disagreement with the government’s theory.
¶25Chambers was an automobile search case, and automobiles have traditionally enjoyed a special status under the fourth amendment. Since prohibition days warrantless searches of motorized vehicles have been upheld “where it is not practicable to secure a warrant because the vehicle can be quickly moved out of the locality or jurisdiction in which the warrant must be sought.” Carroll v. United States, 267 U.S. 132, 153, 45 S.Ct. 280, 285, 69 L.Ed. 543, 551 (1925). Also, during the prohibition era “the car itself . . . was treated somewhat as an offender and became contraband.” United States v. Di Re, 332 U.S. 581, 586, 68 S.Ct. 222, 225, 92 L.Ed. 210, 216 (1948). There is no indication in cases of the Supreme Court or of this circuit that the Carroll doctrine has any applicability to personality other than vehicles mobile because of their locomotive powers.11 Against this historical background, language in Chambers tailored for the law of automobile search is not to be lifted out of context and applied globally to the whole world of personalty not bolted down.
¶26In practice the government’s theory that justification to seize personal effects is ipso facto justification to search them would transform the fourth amendment from the rule to the exception, and, for thousands of items of movable personalty which are routine *476appurtenances of Americans’ day to day life, would read out of the fourth amendment the warrant requirement. Often the police are justified, as in this case, in seizing an article suspected of containing contraband, or evidence or fruits of crime, pending issuance of a warrant. For example, in United States v. Van Leeuwen, 397 U.S. 249, 90 S.Ct. 1029, 25 L.Ed.2d 282 (1970), the Supreme Court upheld temporary detention by customs officials of a suspicious package, mailed first class, pending execution of a warrant to search its contents. See also United States v. Garay, 477 F.2d 1306 (CA5 1973) (No. 72-3537). These legitimate intrusions by way of seizure do not topple like dominoes all remaining privacy interests in the personal effect. As the Supreme Court explained in Chimel v. California, 395 U.S. 752, 89 S.Ct. 2034, 23 L.Ed.2d 685 (1969), there is “no reason why, simply because some interference with an individual’s privacy and freedom of movement has lawfully taken place, further intrusions should automatically be allowed despite the absence of a warrant that the Fourth Amendment would otherwise require.” Id.at 767 n. 12, 89 S.Ct. at 2042, 23 L.Ed.2d at 696 n. 12.12
¶27The fact of a legitimate seizure of personal effects does not, then, automatically justify a subsequent search. By the same measure, there may be cases in which, depending on the facts at hand, a subsequent intrusion will not significantly increase a pre-existing, legitimate interference with a protected interest.13 To recite a familiar principle, “The constitutional validity of a warrantless search is pre-eminently the sort of question which can only be decided in the concrete factual context of the individual case.” Sibron v. New York, 392 U.S. 40, 59, 88. S.Ct. 1889, 1901, 20 L.Ed.2d 917, 932 (1968). The task for us is to determine whether the search significantly added to the invasion of privacy occasioned by the initial seizure, and if so, whether the search was nevertheless within the “scope of the justification for the initial intrusion.” United States v. Green, 474 F.2d 1385 (CA5 1973). See Terry v. Ohio, 392 U.S. 1, 19, 88 S.Ct; 1868, 1878, 20 L.Ed.2d 889, 904 (1968) [“The scope of the search must be ‘strictly tied to and justified by’ the circumstances which rendered its initiation permissible.”]
¶28In this case the search significantly increased the interference with privacy. As a factual matter it differed markedly from the initial seizure, after which the contents of the suitcases remained undisclosed to the world. Moreover, common sense teaches that the citizen whose luggage has been lawfully seized prefers interposition of the judgment of an impartial magistrate before law enforcement officers may rummage through its contents. Also, the search exceeded the scope of the justification for the initial intrusion. While exigent circumstances required seizure of the suitcases and detention pending issuance of a warrant, they did not require an immediate, war-rantless search of the contents.
¶29Thus the search was unlawful because it intruded on an interest protected by the fourth amendment and because a warrant could have been readily obtained without prejudicing the need for effective law enforcement.
¶30c. Automobile cases
¶31As an additional argument, the government cites a line of cases each up*477holding the search of a container which has been found in a vehicle and which contained liquor or other contraband. With one immaterial exception the holdings of these eases are based on the rationale of Carroll v. United States, supra, which generally sanctions warrant-less searches of vehicles stopped on highways and suspected of being used to transport contraband. The focus of analysis in each of these cases was the car itself.14 In this case the government has expressly acknowledged that the subject of the search was the suitcases and has disclaimed the automobile as the subject of search. It has pressed for a ruling on the warrantless search of effects previously removed from the vehicle. While we rarely quote from briefs, we do so here to demonstrate the force with which the government presses for a ruling on the suitcase-search issue without regard to whether a full search of the vehicle would have been legitimate.
Our position is clear if the focus is placed not upon the taxicab, but upon the true subject of the search, the suitcases. . . . [I]n this case the subject of the search was not the vehicle itself, but the luggage known to be conveyed in the trunk. An examination of the movement of the suitcases would indicate that exigent circumstances still existed for the immediate warrantless search of the luggage at the airport notwithstanding the immobilizing of both the vehicle and the occupants.
¶32The government having acknowledged the true subject of the search to be the luggage, we could not, and will not, construct a spurious validation of that search upon the right to search a mobile vehicle which was not the subject of search at all. Cf. United States v. Di Re, 332 U.S. 581, 585-587, 68 S.Ct. 222, 92 L.Ed. 210, 216 (1948).
¶332. The house search
¶34The basis for the motion to suppress fruits of the house search was failure of the warrant to name the executing officer and the affiant.15 On the night of *478January 4 Agent Richel, accompanied by two government attorneys, appeared before a magistrate and secured a warrant to search the Betancourt residence. Ri-chel then radioed agents surveilling the residence that he had secured a search warrant and was en route to serve it. Before he arrived the surveilling agents knocked on the door of the house, and when Betancourt answered they placed her and the other occupants under arrest. The search that yielded the allegedly tainted evidence was not made until Richel’s arrival with the warrant.
¶35Rule 41(c), Fed.R.Crim.P., provides in part: “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.”16 Appellees’ argument appears to be that because the warrant violated this provision, which has the force of statute, see Bacon v. United States, 449 F.2d 933, 937 n. 3 (CA9 1971), evidence taken during execution of the warrant was illegally seized and thus suppressible under Rule 41(e). We do not understand the basis for the motion to be that the warrant contravened the fourth amendment itself, which by its terms does not require that the warrant be directed to a specific officer.
¶36Whether historically or by contemporary usage, the requirement that the serving officer be named in the warrant has come to protect several important interests. As the court explained in United States v. Gannon, 201 F.Supp. 68 (D.Mass.1961), one of its functions is to fix responsibility in the event the warrant is not executed.17 Also, it enables the magistrate to make a pre-search determination that an appropriate officer will serve the warrant. It assists the person whose premises are to be searched in ensuring that the search will be made by an authorized officer and not by an imposter. And it provides a record so that, if necessary, the judicial processes can make a post-search determination that the search was conducted by an authorized officer.
¶37Oral testimony at the motion to suppress hearing shows that in light of these interests the magistrate’s failure to fill in the pertinent blank was a mistake of form only and not of substance. When Agent Richel appeared before the magistrate accompanied by two government attorneys he stated that he, Richel, would be the officer to serve the warrant. Also, Richel showed his identification and the warrant when he arrived at the Betancourt residence, and he told the occupants that he was Special Agent Richel from the Bureau of Narcotics and had been ordered by a magistrate to execute the warrant. At this time the occupants were in the company of other *479agents who had knocked on the door, orally identified themselves as federal narcotics agents, and displayed their identification papers. And, before leaving the residence after the search, Agent Richel and two officers assisting him in the search signed their names on the reverse side of the warrant as the serving officers.
¶38Thus despite technical noncompliance with the Rule, the relevant interests were protected. The magistrate knew in advance who was to serve the warrant, and the designated officer indeed served it; the occupants of the subject premises received a panoply of identifications and confirmations of identity from the serving officer and those assisting him; a record of the name of the serving officer and those assisting him was made by signatures on the reverse side of the warrant; and responsibility for execution of the warrant was fixed. We conclude that not only did defendants receive a full measure of Rule 41(c)’s protection, but that the possibilities of future compliance with the requirement that the serving officer be named in the warrant would not be enhanced by penalizing law enforcement officers who, while not in the precise form required, nevertheless in substance do everything required of them.18 Moreover, we regard as small the possibility of another error of this sort. The search warrant is on a form prescribed by the Administrative Office of the United States Courts, and it has a blank for the name of the serving officer.
¶39Nor is failure of the warrant to specify the name of affiant sufficient ground for suppression in this case. Fed.R.Crim.P. 41(c) provided at the time the search was made that the warrant “shall state . . . the names of the persons whose affidavits have been taken in support thereof.” This provision has been deleted with the 1972 amendments to the Rules of Criminal Procedure. As the Committee’s note to the amended Rule explains:
The requirement that the warrant itself state the grounds for its issuance and the names of any affiants, is eliminated as unnecessary paper work. There is no comparable requirement for an arrest warrant in rule 4. A person who wishes to challenge the validity of a search warrant has access to the affidavits upon which the warrant was issued.
¶40In this case the affiant’s name was affixed to the affidavit, to which defendants have had access. The affidavit did not misrepresent his identity as had the affiant in King v. United States, 282 F.*4802d 398 (CA4 1960), so we are not concerned with a “willfull effort to mask the true source of the information.” Id. at 400-401. See also United States ex rel. Pugh v. Pate, 401 F.2d 6 (CA7 1968), cert. denied, 394 U.S. 999, 89 S.Ct. 1590, 22 L.Ed.2d 777 (1969). At the hearing on the motion to suppress defendants were accorded an opportunity to cross-examine the affiant to the full permissible extent. With the case in this posture we decline to uphold the suppression order for technical noncompliance with a paperwork requirement.
¶413. Conclusion
¶42Affirmed in part, reversed in part, and remanded for further proceedings.
¶73(concurring in part and dissenting in part):
¶74I concur in that part of the opinion of the Court which sustains the validity of the residential search.
¶75I must respectfully dissent from that part of the opinion which invalidates the opening of the suitcases and the examination of their contents.
¶76At Page 4 of the typewritten copy, the majority opinion concedes that the agents had probable cause to believe that the suitcases contained narcotics, that the agents were justified in opening the automobile trunk and removing the suitcases, and that the intrusion into the automobile trunk met the criteria required for a warrantless vehicular search.
¶77In the application of the required standard of reasonableness, what more could have been required?
¶78The majority opinion concludes, however, that although the suitcases were lawfully seized from an automobile they could not, in the absence of a search warrant, be opened. Under the facts of this ease an automobile certainly could have been searched but the majority holds that these suitcases are to be .treated as if they had been seized from such a vehicle, in this instance an automobile at the top of the ramp in front of the Eastern Airlines entrance at an airport. It inescapably follows, I think, that the majority would take the well established law governing warrant-less, probable cause, searches of automobiles and convert into a diametrically opposite rule for the warrantless, probable cause, examination of the contents of packages taken from such vehicles. I have searched in vain for any reported case in the federal judicial system which declares this to be the law; as I understand it, the majority cites none.
¶79Moreover, the majority opinion sets out on this journey in a ease in which it is admitted that we are “without adequate findings below”. Not only that, but the court below originally denied the motion to suppress the contents of the suitcases. A few days later, the ruling was changed for the purpose of making it appealable when the government announced its intention of appealing the residential suppression issue. We ought not to accept appellate jurisdiction under such circumstances. We do not issue advisory opinions. The majority confesses “considerable doubt” of its duty to review the matter.
¶80But to return to the issue which the majority has agreed to decide, I would call attention to the concurring opinion of six Judges of this Court in United States v. Colbert, 474 F.2d 174 (alluded to in Footnote 6 of the majority opinion) in which these Judges would have upheld the warrantless, probable cause, search of brief eases found, not in an automobile, but on a city sidewalk. In my opinion, the suitcases could have been seized and searched as they were leaving the house. That the officers waited until they reached the airport should make no difference.
¶81The majority says that the suitcases should have been detained until a warrant was obtained, that this would have only caused a “temporary delay”. The same could be said for automobiles. Once stopped it is just as easy to detain an automobile as to detain its contents.
¶82The opinion does not say what is to be done with the occupants of a vehicle from which the contents are taken. May they be detained while the warrant is obtained and the search consummated? If it is unreasonable to search a parcel taken upon probable cause from an automobile at the entrance to an airport office then it would be unreasonable to deprive individuals of their liberty while the warrant is obtained. On the oter hand, those in possession of the parcels ought not to be allowed to catch a plane while the hamstrung officer looks for a warrant.
¶83*481It denies reality to say that this automobile was not searched, that only the suitcases were searched. True, the officers knew where to look for the suitcases, but they had to open the trunk of the car to get to them, so this was a search in the customary sense of the term, so held in cases too numerous to mention. The car was stopped, the trunk was-opened, the suitcases were seized.
¶84The majority declines to say that when officers stop an automobile on the probable cause that it contains contraband liquor they must have a search warrant to look in the boxes containing the jugs hidden in the trunk of the car. Why should the law be any different for heroin ?
¶85Reasonableness is the test. If the case were ripe for appellate decision I would, upon the considerations presently available to us, hold the search-of these suitcases to have met every requirement of reasonableness. This is not an ordinary, tin horn heroin case. In the overall picture, nearly four hundred pounds of that deadly stuff was involved.
¶86Since, however, the judgment of the District Court suppressing the contents of the suitcases was clearly entered as an after thought, not as its real opinion in the matter and since it was done solely to engender an appeal not otherwise available, I would remand for adequate findings and for a judgment thereon not prompted by the expressed desire to obtain “a kind of declaratory judgment”.
¶87I respectfully dissent.
