Much has been written about "border searches" and we will not break much new ground here. We believe it appropriate, however, particularly in light of the tragedy of September 11th and the anti-terrorism efforts being made in its aftermath, to reprise what has been written in the course of concluding that the border search at issue here was well within the bounds of law. The order of the District Court will, therefore, be affirmed.

Yvette Bradley, an African-American woman, brought this Bivens action^[1] against the United States, the United States Customs Service, and a number of customs inspectors, supervisors, and officials. She alleged that her constitutional rights were violated when, on April 5, 1999, customs inspectors subjected her to a search of her suitcase, purse and backpack, as well as a patdown, when she arrived at Newark International Airport on a nonstop international flight from the island of Jamaica. Bradley argued that she was selected because of her race and gender, in violation of her equal protection rights under the Fifth and Fourteenth Amendments, and that the patdown was an illegal search under the Fourth Amendment.^[2] The District Court granted defendants' motion for summary judgment, and Bradley now appeals. The District Court had jurisdiction under 28 U.S.C. § 1331 and we have jurisdiction pursuant to 28 U.S.C. § 1291. We review the District Court's grant of summary judgment de novo. Chisolm v. McManimon, 275 F.3d 315, 321 (3d Cir.2001).

While Bradley refers in passing to the search of her luggage, her challenge is directed almost exclusively to the patdown, albeit what she describes as the "intrusive patdown," to which she was subjected at an immigration checkpoint at the Newark International Airport. She argues that in granting summary judgment, the District Court failed to construe the facts in the light most favorable to her as, of course, it was required to do given that she was the non-moving party. The facts as relevant to her Fourth Amendment claim are, however, largely undisputed. Those facts, viewed against well-settled law, defeat that claim.

It is not disputed, for example, that Jamaica is considered by Customs to be a source country for narcotics and that Jamaica Airlines Flight 19, on which Bradley arrived, is considered by Customs to be a high risk flight for narcotics, although Bradley herself does not believe either to be so. It is also not disputed that Bradley was subjected to a patdown, and not a strip search, a body cavity search, or any other type of highly intrusive search. It is not disputed that the patdown was done over Bradley's dress by a female inspector in the presence of a second female inspector and that Bradley's skin was not directly touched in any intimate area. It is not disputed that when the patdown reached what Bradley calls her "groin area," her internal genitalia were not penetrated through the dress. Crediting her version of the facts, the touching that occurred involved the inspector "us[ing] her fingers to inappropriately push on [Bradley's] breasts and into the inner and outer labia," Bradley aff. P 28, the latter concededly part of the external genitalia of a woman.^[3] Bradley, we note, was not wearing underwear and does not dispute that had she been doing so, the additional layer of cloth would have reduced any intrusion that took place. And, of course, Bradley does not dispute that no drugs or other contraband were found.

Neither does Bradley take issue with the law, nor could she, for courts, including our Court, have long held that routine searches at our nation's borders are presumed to be reasonable under the Fourth Amendment. See, e.g., United States v. Ramsey, 431 U.S. 606, 616, 97 S.Ct. 1972, 52 L.Ed.2d 617 (1977); United States v. Hyde, 37 F.3d 116, 118-20 (3d Cir.1994); United States v. Ezeiruaku, 936 F.2d 136, 140 (3d Cir.1991). Immigration checkpoints at international airports are the functional equivalent of national borders. Almeida-Sanchez v. United States, 413 U.S. 266, 273, 93 S.Ct. 2535, 37 L.Ed.2d 596 (1973). As a sovereign state, the United States has the right to "protect itself by stopping and examining persons and property crossing into this country." Ramsey, 431 U.S. at 616.^[4] "Since the founding of our Republic, Congress has granted the Executive plenary power to conduct routine searches and seizures at the border, without probable cause or a warrant, in order to regulate the collection of duties and to prevent the introduction of contraband into this country." United States v. Montoya de Hernandez, 473 U.S. 531, 537, 105 S.Ct. 3304, 87 L.Ed.2d 381 (1985). For example, Congress has empowered border officials to detain and search "all persons coming into the United States from foreign countries." 19 U.S.C. § 1582; see also 19 U.S.C. § 1496 (authorizing customs officials to search the baggage of persons entering the country); 19 C.F.R. § 162.6 (authorizing customs officials to inspect and search all persons, baggage, and merchandise arriving from foreign countries).

It has, of course, also long been true that our nation's historic concern for the integrity of its borders has been "heightened by the veritable national crisis in law enforcement caused by [the] smuggling of illicit narcotics." Montoya de Hernandez, 473 U.S. at 538 (citing United States v. Mendenhall, 446 U.S. 544, 561, 100 S.Ct. 1870, 64 L.Ed.2d 497 (1980)) (Powell, J., concurring). And it is beyond peradventure, as the Seventh Circuit has noted, that "the events of September 11, 2001, only emphasize the heightened need to conduct searches" at our borders. United States v. Yang, 286 F.3d 940, 944 n. 1 (7th Cir.2002).

In Montoya de Hernandez, the Supreme Court's most recent case on border searches, the Court reiterated that, because the Fourth Amendment's balance of reasonableness is qualitatively different at the international border than in the interior, "routine searches" of persons and their effects at the border "are not subject to any requirement of reasonable suspicion, probable cause, or warrant." 473 U.S. at 538 (citing Ramsey, 431 U.S. at 616-19; Almeida-Sanchez, 413 U.S. at 272-73; and Carroll, 267 U.S. at 154). The Court had not previously determined what level of suspicion would justify the detention of an incoming traveler in a nonroutine border search and inspection. In Montoya de Hernandez, however, the Court concluded that an alimentary canal search was not "routine" and is justified only if customs agents reasonably suspect that the traveler is smuggling contraband in his or her alimentary canal. "Reasonable suspicion" was defined as "`a particularized and objective basis for suspecting the particular person'" of smuggling contraband. Id. at 541 (quoting United States v. Cortez, 449 U.S. 411, 417, 101 S.Ct. 690, 66 L.Ed.2d 621 (1981)). The Court explicitly declined, however, to determine, "what level of suspicion, if any, is required for[other] nonroutine border searches such as strip, body-cavity, or involuntary x-ray searches." Id. at 541 n. 4 (emphasis added).

In the course of concluding that an alimentary canal search must be supported by reasonable suspicion, and that reasonable suspicion supported the search of the balloon swallower before it, the Court bemoaned the "subtle verbal gradations" being developed by courts of appeals to enunciate the Fourth Amendment standard of reasonableness which "may obscure rather than elucidate the meaning of the provision in question." 473 U.S. at 541.^[5] The Second Circuit viewed this statement as "warning" against the development of multiple gradations of suspicion to be applied to different types of border searches. United States v. Charleus, 871 F.2d 265, 268 n. 2 (2d Cir.1989).

While we have not had the occasion to address the question left open in Montoya de Hernandez — the level of suspicion, "if any," necessary to conduct at least certain types of nonroutine searches — those court of appeals that have done so agree that reasonable suspicion is required. United States v. Gonzalez-Rincon, 36 F.3d 859, 864 (9th Cir.1994); United States v. Yakubu, 936 F.2d 936, 939 (7th Cir.1991); United States v. Carreon, 872 F.2d 1436, 1442 (10th Cir.1989); Charleus, 871 F.2d at 267; United States v. Oyekan, 786 F.2d 832, 837-39 (8th Cir.1986).

We are not, of course, dealing here with a strip search or a body cavity search or any of the other typical nonroutine searches, but, rather, with a patdown. While the Supreme Court has never articulated what makes a border search routine and has never explicitly classified patdowns as routine, of those courts of appeals which have addressed the patdown issue since Montoya de Hernandez, none has held that a standard patdown at the border is a nonroutine search requiring reasonable suspicion and all have held that such patdowns come within the "routine" border search category and, thus, require no suspicion whatsoever.^[6] United States v. Beras, 183 F.3d 22, 26 (1st Cir.1999); Gonzalez-Rincon, 36 F.3d at 864 (luggage searches and patdowns are routine and do not require reasonable suspicion); Carreon, 872 F.2d at 1442; Oyekan 786 F.2d at 835; c.f. Charleus, 871 F.2d at 268 (the patdown in that case was a routine border search requiring no level of suspicion at all).^[7] We now join those courts, although we do not foreclose the possibility that a patdown gone awry could become so intrusive as to become a nonroutine search requiring application of the reasonable suspicion standard.^[8]

This, says Bradley, was just such a case, with the patdown to which she was subjected so intrusive that, although it was concededly not a body cavity or strip search, it became "nonroutine," thereby requiring reasonable suspicion which, she argues, did not exist. We need not decide whether the customs inspectors reasonably suspected that Bradley was smuggling contraband because we conclude that the patdown was not so intrusive as to be transformed into a nonroutine border search.

Bradley has not pointed us to any court of appeals' decision subsequent to Montoya de Hernandez which has held that on a border search even an "intrusive" patdown is nonroutine and must be supported by reasonable suspicion. See n. 9 infra. Rather, she relies for this proposition on Anderson v. Cornejo, 199 F.R.D. 228 (N.D.Ill.2000), a decision which simply does not do for Bradley what it did for the one named plaintiff in that class action who survived a motion for summary judgment. Viewing the facts in her favor, the District Court found that the plaintiff was subjected to an intrusive patdown search which involved the customs inspector pushing her hand through plaintiff's clothes and her finger into plaintiff's vagina six times causing pain. The Court found that this was "close enough to a cavity search and done repeatedly enough to be more than just a standard patdown search," 199 F.R.D. at 260-61, and that reasonable suspicion did not exist. The Court noted two other types of conduct that, in its view, would cause a patdown to become so intrusive that it could be justified only by reasonable suspicion. First, it suggested that a patdown in which an "inspector reaches under the traveler's clothes, particularly in the breast and crotch area" would require reasonable suspicion. Id. at 258. As an example, the Court cited an earlier incarnation of Saffell v. Crews, discussed above in note 8, where Saffell alleged (an allegation later disproved at a bench trial) that "the inspector reached under Saffell's bra and under her underwear, examining Saffell's entire pubic area and inserting her finger in Saffell's vagina." Id. at 258 n. 33. Second, the Court suggested that the "[f]ondling of a traveler's genital area, breasts, or buttocks area during a patdown would also constitute an intrusive patdown." Id. at 258. The Court defined "fondling" as touching "in a sexual or sexually suggestive manner." Id. at 259. It noted, however, that even an "aggressive" patdown in the crotch or breast area would be sufficiently intrusive to require reasonable suspicion. Id. Anderson, we reiterate, is the sole decision on which Bradley's argument depends. There is, however, nothing in Anderson, either in the conduct it was reviewing or in the conduct that it hypothesized could warrant relief, that comes close to that which Bradley describes. While, as the District Court observed in Bradley's case, "[p]enetration of [a woman's] internal genitalia, absent reasonable suspicion, would in all likelihood constitute an unreasonable search," JA28-29, customs officials as a matter of standard procedure are permitted to feel over clothing for bulges in an area known by them as a common place for hiding contraband. JA29. That is precisely what they did here, and the District Court correctly rejected Bradley's Fourth Amendment claim.

This was, no doubt, a disagreeable experience for Bradley. That it was not, in our view, a constitutional violation does not mean, in the words of the Saffell Court, "that Customs agents have free license to exceed what is reasonable and proper under the law in order to accomplish their important responsibilities. They must be sensitive to their intrusive powers and not abuse and misuse those powers...." Saffell, 183 F.3d at 659.

One final note. The District Court concluded that even if Bradley had made out a prima facie claim of a constitutional violation, the three named customs inspectors would be entitled to qualified immunity. Given our conclusion that no Fourth Amendment violation was stated, we need not reach this issue. We note, however, that in April 1999, when Bradley arrived at the Newark International Airport, there was no law post-Montoya de Hernandez, much less "clearly established" law, that at our nation's borders even an intrusive patdown search was anything other than "routine" such that it required reasonable suspicion.^[9]

The fact that there was no Fourth Amendment violation does not mean that one was not discriminatorily selected for a search. Bradley alleges that the defendants violated her right to equal protection under the Fifth and Fourteenth Amendments to the United States Constitution when customs officials selected her for a luggage and then a patdown search because she was an African-American female.^[10] To make an equal protection claim in the profiling context, Bradley was required to prove that the actions of customs officials (1) had a discriminatory effect and (2) were motivated by a discriminatory purpose. Arlington Heights v. Metro. Housing Dev. Corp., 429 U.S. 252, 264-66, 97 S.Ct. 555, 50 L.Ed.2d 450 (1977) (race discrimination); Washington v. Davis, 426 U.S. 229, 239-42, 96 S.Ct. 2040, 48 L.Ed.2d 597 (1976) (race discrimination); Chavez v. Illinois State Police, 251 F.3d 612, 635-36 (7th Cir.2001) (racial profiling) (citing Personnel Adm'r of Mass. v. Feeney, 442 U.S. 256, 272-74, 99 S.Ct. 2282, 60 L.Ed.2d 870 (1979)) (gender discrimination). Bradley's equal protection claim is bereft of proof.

To prove discriminatory effect, Bradley had to show that she is a member of a protected class and that she was treated differently from similarly situated individuals in an unprotected class. Chavez, 251 F.3d at 636; see also United States v. Armstrong, 517 U.S. 456, 469, 116 S.Ct. 1480, 134 L.Ed.2d 687 (1996); Andrews v. City of Philadelphia, 895 F.2d 1469, 1478 (3d Cir.1990). Bradley, an African-American woman, is clearly a member of a protected class. Thus, our sole inquiry under this prong of the analysis is whether Bradley submitted evidence that customs officials treated her differently from similarly situated members of an unprotected class. Discriminatory effect may be proven by naming similarly situated members of an unprotected class who were not selected for the same search or, in some cases, by submitting statistical evidence of bias. Chavez, 251 F.3d at 636.^[11]

While her primary complaint is, again, directed to the patdown, Bradley also argues that customs officials selected her for the luggage search based on the fact that a group of unidentified but similarly situated white males — similarly situated because they were wearing baseball caps while she was wearing a wool designer hat with two braids hanging down the sides — were not selected to have their luggage searched. Even if we assume that the white males were similarly situated, an assumption we are somewhat loathe to make, Bradley failed to submit any evidence that she was unfairly singled out. The mere fact that a few unidentified white males on a flight of many passengers were not selected when Bradley was does not, without more, demonstrate a discriminatory effect. As to her selection for a patdown search, Bradley has conceded that the only other person on her flight of whom she was aware who was selected for a patdown search was a white male who, we note, was found carrying drugs. This certainly does not indicate discrimination. Finally, Bradley failed to submit any statistical evidence of bias. There was, then, no evidence of discriminatory effect before the District Court.

Bradley does not contest this conclusion; rather, she argues that she failed to meet her burden of proof because the District Court restricted discovery and then granted summary judgment prematurely. "[W]e review a claim that the district court has prematurely granted summary judgment for abuse of discretion." Pastore v. Bell Telephone Co. of Penn., 24 F.3d 508, 510 (3d Cir.1994). Although Bradley claims that additional discovery was critical to her case, she failed to file an affidavit pursuant to Federal Rules of Civil Procedure 56(f) identifying "with specificity what particular information is sought; how, if uncovered, it would preclude summary judgment; and why it has not previously been obtained." St. Surin v. Virgin Islands Daily News, Inc., 21 F.3d 1309, 1314 (3d Cir.1994) (citation and internal quotations omitted). We have made clear that, in all but the most exceptional cases, failure to comply with Rule 56(f) is fatal to a claim of insufficient discovery on appeal. Pastore, 24 F.3d at 511 (citing Falcone v. Columbia Pictures Indus., Inc., 805 F.2d 115, 117 n. 2 (3d Cir.1986)). While Bradley argues that she constructively met the Rule 56(f) affidavit requirement, we have generally rejected constructive compliance arguments. See e.g., Radich v. Goode, 886 F.2d 1391, 1394 (3d Cir.1989). Given the strong presumption against a finding of constructive compliance with Rule 56(f), the District Court did not abuse its discretion when it granted summary judgment without allowing additional discovery.^[12]

Evaluating the record that was before the District Court, we conclude that Bradley failed to present evidence that, when viewed in the light most favorable to her, would demonstrate a "discriminatory effect." Accordingly we need not determine, as the District Court did not need to determine, whether the customs officials acted with a "discriminatory purpose" when they selected Bradley for the luggage and patdown searches.

The order of the District Court will be affirmed.
