Three of the defendants in this
Bivens
action have taken interlocutory appeals, contending that they are entitled to qualified immunity. The plaintiffs are 90 American citizens who were searched at O’Hare Airport between March 1996 and August 1999 when reentering this country after foreign travel. They contend that Customs personnel chose them for non-routine searches (pat-downs, strip searches, x-ray inspections, or body-cavity searches) because of their race and sex (the plaintiffs are black women) rather than because of reasonable suspicion that they were violating the law. None of the searches detected any contraband in the plaintiffs’ possession. What is more, plaintiffs contend, inspectors were more likely to act on suspicion with respect to black women than with respect to black men, white women, or any other combination of attributes. The selection practices at O’Hare between 1995 and 1999 (the period covered by the complaint) thus violate the equal protection component of the fifth amendment’s due process clause, plaintiffs maintain. Appellants were managers and did not target any of the plaintiffs for search or perform any of those searches. Their argument starts from the rule that there is no vicarious liability in
Bivens
litigation, which means that they may be held liable only for their own conduct — and none of that conduct would have alerted a reasonable person to the risk of liability, appellants contend. If that is so, then they are entitled to immunity. See, e.g.,
Saucier v. Katz,
Because the first issue when a defendant invokes immunity is whether the conduct alleged in the complaint violates the Constitution, see
Saucier,
Resolution of this problem starts with separating factual and legal components of the claim for relief. ‘We didn’t do it” may be a good defense, but it is unrelated to immunity (a doctrine designed to protect public officials from the effects of guessing wrong in a world of legal uncertainty) and thus,
Johnson
held, not a proper ground of interlocutory appeal.
Johnson
precludes the managerial defendants from denying that the line inspectors used race and sex as selection criteria. Plaintiffs believe that, if we must assume that racial discrimination occurred on defendants’ watch, and they did nothing to stop it, there could be no point to the appeal. We should just let the case proceed to trial. Recognizing the force of
Johnson,
the managers concede (for purpose of the appeal only) that some line inspectors at O’Hare behaved unconstitutionally, and they further concede (again
arguendo)
that they did not lift a finger to rectify the problem. There remains a
bona fide
question about legal doctrine, and thus about immunity: would
*1023
reasonable persons, knowing what the managers knew (or were bound to learn), have recognized that the Constitution required them to intervene? We may address that question without transgressing
Johnson,
and as in
Saucier
may give either of two answers: first, that taking all evidence in the light most favorable to the plaintiffs there was no requirement to act; or, second, that there is such a requirement but that a reasonable person would not have understood at the time that the law required this. Thus it is possible, consistent with
Johnson,
to cover the question whether the plaintiffs have a good legal theory as well as the immunity defense; but, as
Johnson
and
Saucier
hold, see
Application of this normal summary-judgment standard does not mean, however, that all evidence is equally helpful to the plaintiffs. Plaintiffs point to data collected by the General Accounting Office and described in its report
U.S. Customs Service: Better Targeting of Airline Passengers for Personal Searches Could Produce Better Results
(2000). They submit that these data show systematic constitutional violations by the Customs Service— the sort of violations that managers must know about and act to prevent. The district judge wrote that “Black women were ... the racial/gender group of United States citizens most likely to be X-rayed (6.4%), a rate more than 8 times that of White women (0.73%) and almost 12 times that of White men (0.53%), as well as 39% higher than Black men (4.6%).”
These and similar data from the GAO’s report do not support any constitutional claim against the appellant managers, for at least four reasons. First, the report was not published until March 2000, while the last search contested in this litigation occurred in August 1999. (During May 1999 the Customs Service announced a review of its criteria for conducting non-routine inspections; plaintiffs do not contest the policy that was implemented as a result of this process.) Plaintiffs do not contend that the Customs Service had any equivalent compilations in its possession earlier, and there was accordingly no reason for the managers to know these statistics in time to have done plaintiffs any good. See
Fourth, these statistics show disparate impact, not disparate treatment, and the equal protection guarantee is concerned only with the latter. See
Washington v. Davis,
Data from the GAO’s report do not imply that Customs officials are searching black women (or any other group) but not similarly-situated passengers in other groups. The report’s outcome-by-group tables — we gave one example above, concerning the success rate of strip searches — show that Customs officials search black women with (on average) the same degree of suspicion that leads them
*1025
to search white women or white men. A 27.6% success rate for a particular kind of border search is not to be sneezed at. It may imply that the Customs officials are conducting too few searches, not too many. (The GAO recommended that the Customs Service increase the number of searches in high-success-rate categories.) Other searches, with far lower rates of success, have been held constitutional. See, e.g.,
United States v. Martinez-Fuerte,
Because the data in the GAO’s report do not imply that any of the defendants engaged in (or had knowledge of) discrimination based on race or sex, we must analyze separately what each of the three appellants may have known or done. Robert Trotter is the first. Between June 1997 and February 1999, Trotter was the Assistant Commissioner of Field Operations. Based in Washington, D.C., Trotter reported directly to the Commissioner of Customs. The district court granted summary judgment in Trotter’s favor except for claims raised by any plaintiff strip searched after July 21, 1998. On that date Trotter received an email message from Garrett Fee, his immediate subordinate (with responsibility for the Midwest, including O’Hare Airport), telling him that Senator Carol Mosley Braun had scheduled, and then cancelled, a meeting to discuss passenger-search practices at O’Hare. That email, which noted that 54 black women arriving from Jamaica had been searched during 1997, should have led Trotter to inquire whether searches had been based on race or sex, the district court thought. We need not decide whether this is a good constitutional theory, because plaintiffs’ appellate brief abandons the suit against Trotter: “Only one plaintiff was strip searched after July 21, 1998 and plaintiffs have decided not to challenge the appeal from the denial of immunity for strip searches after July 21, 1998.” Brief 1 n. 1. We read this as a promise to dismiss the complaint with respect to Trotter, and on that understanding we need not consider the substance of his arguments.
Sergei Hoteko, the second appellant, was Chief Inspector of Passenger Operations for the Port of Chicago between July 1995 and June 1999. On May 24, 1997, five passengers arriving from Jamaica (four of them black women) were found to be carrying concealed drugs on (or in)
*1026
their persons. During the ensuing four months, black women arriving from Jamaica were subject to non-routine searches more frequently. Between January 1995 and May 14, 1997, about 9.5% of all strip searches at O’Hare were of black women; that figure rose to 16.2% between May 15 and September 15, 1997, and fell to 8.7% for September 16, 1997, through April 2000. The district court concluded that this four-month peak violated the Constitution and that a reasonable jury might think Hoteko responsible for it.
Perhaps Johnson v. Jones precludes a close search of the record to find out just what Hoteko knew and what he told his subordinates to do. It does not, however, preclude a strictly legal ruling: That urging inspectors to conduct more of a kind of search that has been successful does not violate the Constitution. Plaintiffs do not contend that Hoteko told any inspector to single out black women. They contend, rather, that Hoteko and other persons at the meeting would have discussed multiple characteristics of the five persons caught smuggling on May 24, 1997: race; sex; age; occupation; origin of travel; length of stay; explanation for trip; number, timing, and destination of other international journeys; how and when the tickets were purchased; and other details. Nothing in this episode suggests that anyone was selected because of race or sex, as opposed to reasonable suspicion that smuggling was ongoing. Plaintiffs have offered no statistical analysis of the data; for all we know (and for all Hoteko could have known), race and sex played no explanatory role. These attributes may have been correlated with others that are in turn linked to the probability of finding contraband. As we have pointed out, disparate impact does not imply disparate treatment, and plaintiffs have offered nothing to show that Hoteko knew about, or urged anyone to practice, disparate treatment. This evidence therefore would not allow a reasonable jury to conclude that Hoteko sponsored, encouraged, or failed to stop, disparate treatment of arriving passengers. Plaintiffs’ contention that Hoteko attended other meetings at which the race and sex of persons searched was discussed adds nothing: Bass, Armstrong, and Fee-ney show that knowledge of disparate impact (if that can be imputed to Hoteko) is not knowledge of, let alone support for, disparate treatment.
Plaintiffs tell us that Hoteko “paid no attention to the efficacy of Customs searches” (Br. 14), which goes far to demonstrate that he cannot have engaged in disparate treatment of black women. According to plaintiffs, however, what this shows is that Hoteko “turned a blind eye” toward the problem and thus became liable. Opinions often say that averting one’s eyes for fear of what one would see is a form of knowledge, e.g.,
United States v. Ramsey,
Hoteko supervised Patrick Noonan, the third appellant. Noonan, the Passenger Service Representative at O’Hare Airport, was in charge of the large staff of inspectors who dealt'with arriving passengers. The district court concluded that Noonan could be culpable for failing to act on complaints from arriving passengers alleging that inspectors engaged in discrimination. See
We may assume, as the district court concluded, that Noonan “repeatedly performed superficial and inadequate investigations.” Yet, as the district judge recognized, few of the 12 complaints alleged the combination of race and sex discrimination that concerns plaintiffs. This makes it impossible to task Noonan with deliberate indifference toward the complained-of discrimination. “Deliberate indifference” means subjective awareness. See
Farmer v. Brennan,
What we have said so far covers the district court’s explanation for keeping Noonan and Hoteko in the case. Plaintiffs have all but abandoned the district judge’s rulings concerning Hoteko, however. Instead of defending the ground on which they prevailed, plaintiffs offer a number of arguments that were presented to, and rejected by, the district court. They are entitled to do so; any argument presented to the district court may be urged in support of the judgment without need to take a cross-appeal. See
Massachusetts Mutual Insurance Co. v. Ludwig,
*1028
which is not allowed; at all events, our decision in Noonan’s favor redounds to Hoteko’s benefit as well. Plaintiffs assert that Hoteko knew even apart from the events of May 24, 1997, that black women were being searched in disproportionate numbers; once again, however, knowledge of disparate impact is not knowledge of disparate treatment. According to plaintiffs, one line inspector had complained to Hoteko that others were discriminating. Hoteko referred this complaint to an internal investigator, who determined that it was unfounded. The district court sensibly concluded that the incident cannot be relied on to show that Hoteko knew about, or was culpable for, inspectors’ discrimination.
The decision of the district court with respect to Hoteko and Noonan is reversed. The decision with respect to Trotter is vacated, and the matter is remanded so that the plaintiffs may dismiss their complaint with respect to him.
