As a result of an airport security search which discovered not weapons but drugs, Lee Skipwith III was charged with and convicted of the possession of cocaine in violation of 21 U.S.C. § 844(a). He contends here that the evidence should have been suppressed, arguing that the search was unconstitutional. We hold that the search was lawful and that the contraband uncovered by it was properly admitted in the court below; thus we affirm.
On May 19, 1971, the defendant presented himself for boarding at the Eastern Airlines boarding gate at the Tampa International Airport, a place at which he knew or should have known he was subject to being searched. Because he met the F.A.A. anti-skyjack profile and stated he had no identification, the Eastern boarding agent detained him and called in a deputy United States marshal. The marshal, Rodriguez, asked the prospective passenger his name. The response was “S. Jackson.” This *1274name corresponded to the name on the ticket which the defendant presented. Upon further inquiry, the defendant informed the marshal that he had no identification. The marshal thereupon inquired as to whether a billfold-shaped bulge which was visible in the left rear pocket of defendant’s tight-fitting trousers contained any identifying papers. Defendant acknowledged that the bulge was produced by a wallet, but insisted that there were no identifying papers in it since he had left his identification in St. Petersburg. The marshal insisted that he produce the wallet. Skipwith then confessed: “That [S. Jackson] isn’t my name. That’s my traveling name. My true name is Skipwith.” With this disclosure, the marshal directed Skipwith to come with him to a private office. On the way to the office, another deputy marshal, Hardman, called Rodriguez’ attention to a visible bulge in Skipwith’s right front trouser pocket which was about three inches long and two inches thick. In the office Rodriguez examined the wallet and determined that it contained identification papers bearing the name Lee Skipwith III. According to Rodriguez’ testimony, Skipwith was very nervous and appeared to be under the influence of either alcohol or some other drug. Rodriguez then ordered Skipwith to stand up and empty his pockets. Rodriguez testified that he “was inclined to believe that he had a gun in that pocket.” Instead, the search revealed a plastic bag containing some white powder which was later determined to be cocaine.

This court has recently discussed the permissible scope of airport searches in United States v. Moreno, 475 F.2d 44 (5th Cir. 1973). In that case the court held that suspicious activity by the defendant, a ticketed passenger, in the airport lounge area and en route toward a boarding gate made the security officers’ search of the defendant’s person a reasonable one. Relying on the rationale of Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), the court weighed the competing interests of law enforcement in the context of the present air piracy problem against the rights of individuals using the airport; it concluded that airport searches designed to protect the heavy volume of interstate and foreign travel by air could be conducted under a less stringent standard than ordinary probable cause because of the unique circumstances of time and place.1
In Moreno constitutional reasonableness was found in suspicious activity by a ticketed passenger headed toward a boarding gate but still in the general airport area. Today we are called upon to apply the same standard of reasonableness to a situation factually unlike Moreno. Here the defendant, Skipwith, had actually presented himself at the boarding gate as a potential passenger. He could not have been where he was to look around, to greet friends or relatives or to say farewell. His only reason for being there had to be to board the aircraft. Because of the widespread publicity given to the government’s efforts to cope with the piracy of aircraft, it was general knowledge that citizens boarding planes were subject to special scrutiny and to weapon searches. Unlike Moreno or Legato the officer did not go to Skipwith and stop and search him at a point where such a procedure was extraordinary or unexpected. Rather, Skipwith came to the specific part of the airport where he knew or should have known all citizens were subject to being searched.
Since Skipwith exhibited characteristics which corresponded to the F.A.A.’s *1275likely skyjacker profile, it may be that this was all that was needed to validate his detention and search here. Undoubtedly this profile, developed from a distillation of characteristics attributable to previous skyjackers, is a valuable and useful tool in the hands of the airport security officers.2 However, the factual matrix of the case at bar makes it unnecessary for us to decide whether an airport search based on the profile alone would satisfy the test of reasonableness in all cases.
The government contends that, in light of the magnitude of the perils created by air piracy, searches of boarding passengers are controlled by the same standard applied to customs searches at the national border — mere or unsupported suspicion.3 Bitter experience has taught us that the physical dangers of mass kidnapping and extortion posed by air piracy are even greater than the dangers against which the usual border search is directed. Necessity alone, however, whether produced by danger or otherwise, does not in itself make all non-probable-cause searches reasonable.4 Reasonableness requires that the courts must weigh more than the necessity of the search in terms of possible harm to the public. The equation must also take into account the likelihood that the search procedure will be effective in averting the potential harm. On the opposite balance we must evaluate the degree and nature of intrusion into the privacy of the person and effects of the citizen which the search entails.
lit undertaking our calculation of the weight to be accorded to these three factors in the case at bar — public necessity, efficacy of the search, and degree of intrusion — we need not reiterate what was said in Moreno about the dangers posed by air piracy; suffice it to say that there is a judicially-recognized necessity to insure that the potential harms of air piracy are foiled. The search procedures have every indicia of being the most efficacious that could be used. The group being screened is limited to persons with the immediate intention of boarding aircraft. Metal detectors, visual inspection, and rare but potential physical searches appear to this court to provide as much efficiency to the process as it could have.5
On the other side of the judicial scales, the intrusion which the airport search imposes on the public is not insubstantial. It is inconvenient and annoying, in some cases it may be embarrassing, and at times it can be incriminating. There are several factors, however, which make this search less offensive to the searched person than similar searches in other contexts. One such factor is the almost complete absence of any stigma attached to being subjected to search at a known, designated airport search point. As one commentator has put it in the border search context, “individuals searched because of their membership in a morally neutral class have less cause to feel insulted. . . . ”6 In addition, the offensiveness of the screening process is somewhat mitigated by the fact that the person to be *1276searched must voluntarily come to and enter the search area. He has every opportunity to avoid the procedure by not entering the boarding area. Finally, the circumstances under which the airport search is conducted make it much less likely that abuses will occur. Unlike searches conducted on dark and lonely streets at night where often the officer and the subject are the only witnesses, these searches are made under supervision and not far from the scrutiny of the traveling public. Moreover, the airlines, which have their representatives present, have a definite and substantial interest in assuring that their passengers are not unnecessarily harassed. The officers conducting the search under these circumstances are much more likely to be solicitous of the Fourth Amendment rights of the traveling public than in more isolated, unsupervised surroundings.
Our conclusion, after this tripartite weighing of the relevant factors, is that the standards for initiating a search of a person at the boarding gate should be no more stringent than those applied in border crossing situations. In the critical pre-boarding area where this search started, reasonableness does not require that officers search only those passengers who meet a profile or who manifest signs of nervousness or who otherwise appear suspicious. Such a requirement would have to assume that hijackers are readily identifiable or that they invariably possess certain traits. The number of lives placed at hazard by this criminal paranoia forbid taking such deadly chances. As Judge Friendly has stated:
Determination of what is reasonable requires a weighing of the harm against the need. When the object of the search is simply the detection of past crime, probable cause to arrest is generally the appropriate test. When the risk is the jeopardy to hundreds of human lives and millions of dollars of property inherent in the pirating or blowing up of a large airplane, the danger alone meets the test of reasonableness, so long as the search is conducted in good faith for the purpose of preventing hijacking or like damage and with reasonable scope and the passenger has been given advance notice of his liability to such a search so that he can avoid it by choosing not to travel by air.
United States v. Bell, 464 F.2d 667, 675 (2d Cir. 1972) (concurring) (footnote omitted). Thus, while Moreno established that searches of certain persons in the general airport area are to be tested under a case-by-case application of the reasonableness standard, we hold that those who actually present themselves for boarding on an air carrier, like those seeking entrance into the country, are subject to a search based on mere or unsupported suspicion.
The distinction we draw between a person entering any specific area- — here the boarding gate — where searches are regularly conducted and one like Moreno who was in an airport restroom is analogous to that drawn in United States v. Thompson, 475 F.2d 1359 (5th Cir. 1973). There the court pointed out the distinction between searches made at the nation’s borders and those which are made within the interior of the country. “Searches in this undefined zone [remote from but near the border] must be reasonable upon all of the facts, one consideration being the proximity of the search to an international border. . When acting in this expanded border search area, the customs agents must have a ‘reasonable suspicion’ that the customs laws are being violated.” 475 F.2d at 1362. Searches at the border proper, on the other hand, may be conducted “where there is a ‘mere suspicion’ of possible illegal- activity.” 475 F.2d at 1361. The logic which supports the application of this border search distinction to the standards governing airport searches is readily apparent. The public is assured that the net can sweep no wider than necessary since the broad right to search is limited to the last possible point in time and space which could protect the aircraft, the boarding *1277gate (or secure corridor entrance). Thus, no mere passerby will be subjected to this search — only those in the act of boarding planes could be involved. The merits of Skipwith’s claim that this particular search would have been unreasonable before he passed the locus poeni-tentiae — the point at which he presented himself as a passenger for boarding— are hypothetical. There is simply no need to determine whether this search satisfied the Morewo-established standard for airport area searches, because Skipwith had presented himself as a prospective passenger at the boarding gate.
Skipwith further contends that even if some search were justified, the search actually undertaken exceeded the scope of the justification. He argues that the officer was constitutionally limited to conducting a frisk or pat-down for weapons rather than demanding that he empty his pockets. As Moreno pointed out, however, a hijacker’s arsenal “is not confined to the cumbersome gun or knife; for modern technology has made it possible to miniaturize to such a degree that enough plastic explosives to blow up an airplane can be concealed in a toothpaste tube. A detonator planted in a fountain pen is all that is required to set it off. . . . It is in this context that we must assess the constitutionality of the search. . . .” 475 F.2d at 49. The range and variety of devices real and simulated which can be used to intimidate the crew of an aircraft when it is aloft are almost limitless. The airport security officer has to be alert for all of them. Marshal Rodriguez was justified in undertaking a search with sufficient scope to reveal any object or instrumentality that Skipwith could reasonably have used to effect an act of air piracy. Here the search object — which created a three-inch-long, two-inch-thick bulge— was clearly within that limit.
Moreover, Judge Simpson and I fully concur in that part of Judge Aldrich’s opinion which holds that Skip-with’s right-to-leave argument is devoid of merit. Thus, this court expressly declines to follow the rule announced in United States v. Meulener, 351 F.Supp. 1284 (C.D.Cal.1972). Cf. United States v. Legato, supra, 480 F.2d at 413 and n. 8.
II.
Skipwith contends that, even if a weapon discovered during his search could have been introduced into evidence, the cocaine should have been excluded since the search was not and could not have been conducted for the purpose of discovering illicit drugs. In light of Judge Aldrich’s dissent, it is appropriate to discuss more fully than would otherwise be indicated our holding that the product of this valid search was properly admitted into evidence.
Under the pressure of a search for truth and in light of a growing skepticism as to both its necessity and efficacy, the exclusionary rule is waning, not waxing, in the law today. See, e. g., Wright, Must the Criminal Go Free if the Constable Blunders? 50 Tex.L.R. 736 (1972). “Proper adjudication of cases in which the exclusionary rule is invoked demands a constant awareness of [its] limitations.” Terry v. Ohio, supra, 392 U.S. at 14, 88 S.Ct. at 1876; United States v. Ragsdale, 470 F.2d 24, 30 (5th Cir. 1972). The strictures of the Fourth Amendment protect the citizen from unwarranted and unreasonable intrusion by the government on his person or into his effects. The rule excluding the admission of illegally obtained evidence was designed to effectuate this purpose by removing the principal incentive to conduct illegal searches. The rule does not exist because the evidence is not probative, or to chastise errant law officers, or to benefit the accused.
While the force of Judge Aldrich’s admonition that “due process demands that the imposition on the citizen be no greater than the occasion requires” cannot be disputed, it is important to note that the imposition which must be con*1278sidered is the intrusion on a citizen’s right to be free of unreasonable searches, not upon any right to be free of criminal prosecution. Certainly the imposition of a criminal penalty for possession of drugs found during an airport search will burden the one on whom it is imposed; constitutionally speaking, however, he has suffered only the same intrusion as other passengers who were searched. Although the discovery of cocaine in a search for weapons may be unexpected by the government, there is nothing in the Constitution that gives the apprehended felon a right to complain because the product of the protective action was not anticipated. Such a result cannot properly be classified as a windfall. It is the product of valid police work. The government has no duty to catch a carrier of dope sportingly or aecoi'ding to any game book rule. Nor is it material whether the circumstances leading to the discovery of the cocaine were of the defendant’s making; all that matters is that the search be legally conducted.
We are asked to exclude the evidence of crime obtained in a concededly valid seach in order to enhance the overall reasonableness of the search procedure. The basis on which we are urged to adopt this would-be exception to the general exclusionary rule is that the relaxed standards of airport searches require a different calculus in evaluating their purpose. It is said that in airport search situations, where relatively inflexible probable cause is displaced by its more mutable concomitant — reasonableness'— as the standard validating the search, the real utility of the exclusionary rule lies not in discouraging illegal searches, for there are relatively few of those, but rather in discouraging the pretextual search — that is, the search outwardly appearing to be conducted to discover weapons in the skyjacker’s arsenal which really seeks contraband or evidence for which only a warranted or probable cause search would be lawful. The basis for excluding any evidence other than skyjack weapons detected during desirable and necessary anti-piracy searches is that this exceptional exclusion will destroy the incentive for officers to conduct pretextual searches.
This argument has never been accepted by any court7 and it was just rejected by this court in Moreno and Legato in situations completely analogous to the one presented here. Even were the precedents not so clear, such a departure from the established rule is not justified. Assuming arguendo that a significant number of airport searches are actually conducted to discover evidence or contraband rather than skyjack weapons (a premise which has by no means been established), it does not follow that the suggested rule would be a significant deterrent of that behavior.
The exclusionary rule necessarily deters only those searches which have as their object the production of evidence for the purpose of conducting a successful criminal prosecution. The fact is, however, that searches may be and are conducted for other purposes. In the performance of their duty to apprehend, not prosecute, the searching officer may neither know nor care whether the offender is actually convicted. In addition, if we are to postulate that some significant number of pretextual airport searches are conducted, then we should also assume that officers may from time to time make searches and seizures for reasons other than those relating to criminal prosecution, perhaps to seize suspected contraband or with no purpose *1279other than to harass certain individuals. Moreover, since the airport boarding gate search will usually be legally authorized, a declaration by the court that certain of its fruits are inadmissible will carry with it neither the moral censure nor the threat of disciplinary action or civil suit implicit in a judicial application of the conventional exclusionary rule, where the court’s adjudication that the evidence is inadmissible also amounts to a determination that the officer exceeded his authority. Thus, in reckoning what could be, it seems most likely that the proposed rule would have very little deterrent effect on a pretextual airport search. Without the slightest intent to approve any misuse of airport search authority, we must recognize that “a stern refusal by this Court to condone such activity does not necessarily render it responsive to the exclusionary rule.” Terry v. Ohio, supra, 392 U.S. at 14, 88 S.Ct. at 1876, 20 L.Ed.2d 889.
Professor Wright’s observation on the efficacy of the exclusionary rule in general is particularly pertinent to its proposed application here.
[I]t can be fairly said of the Exclusionary Rule that it cannot be proved to have a significant deterrent effect and this effect is not so inherently likely that we can assume it to exist in the absence of proof.
50 Tex.L.R. at 741. Were there no societal costs in adopting the rule contended for, the speculative possibility that some undesirable searches would be discouraged might justify its imposition. The fact is, however, that the rule would allow a significant number of crimes to go unpunished though the authorities may have lawfully obtained all of the evidence necessary to establish the guilt of the offenders. The unproven potential of this variant on the exclusionary rule simply does not justify the public detriment in allowing this class of criminals to go unconvicted.
No one can gainsay that airport searches are annoying. Certainly all citizens look forward to the day when skyjackings and their sequels, airport search and security measures, cease. When the threat of air piracy disappears the standards of reasonableness which we here recognize will go with it. Until that time arrives, however, the portent for evil supplies the requisite Fourth Amendment reasonableness to justify the search of any person who presents himself at a boarding gate to enter an aircraft.
In light of our holdings that the search was valid and that there was no error in the admission into evidence of the contraband discovered, the conviction of Lee Skipwith III is
Affirmed.
. Even more recently this court followed Moreno in United States v. Legato, 480 F.2d 408 (5th Cir. 1973). In Legato the court held that suspicious conduct and an informer’s tip justified the airport parking lot search of one who had been to the boarding area but at the time of the search was apparently preparing to get into a car and leave the airport.
. See United States v. Lopez, 328 F.Supp. 1077 (E.D.N.Y.1971).
. The fact that one is in the process of crossing an international boundary provides sufficient reason in itself to permit a search for aliens or contraband, without the presence of any other circumstances that would normally have to attend the requirements of the Fourth Amendment.
United States v. McDaniel, 463 F.2d 129, 132 (5th Cir. 1972).
. For example, no court has ever approved a dragnet search of all citizens in a high-crime area of any urban center, based upon the ’justification that the danger of criminal conduct would be reduced.
. The record in this case contains no direct proof of results of such procedures, but it is a matter of general knowledge that the incidence of air piracy has dramatically decreased since the institution of stricter airport security measures at the beginning of 1973.

. As Judge Aldrich points out in his dissent, the majority opinion in Sibron v. New York, 392 U.S. 40, 88 S.Ct. 1889, 20 L.Ed.2d 917 (1968), the companion case to Terry, did not reach the issue of the admissibility of contraband seized during a Terry self-protective search. However, the three separate opinions of Justices White, 392 U.S. at 69-70, 88 S.Ct. at 1905, Harlan, 392 U.S. at 79, 88 S.Ct. at 1910, and Black, 392 U.S. at 79-80, 88 S.Ct. at 1910-1911, assumed it would have been admissible as a matter of course.
