This is the last in a series of three cases we decide today relating to the qualified immunity defense in the national security context.
See Halperin v. Kissinger (“Halperin II”),
*206 I
This case, the factual background of which is recited more fully in our earlier decision,
see Ellsberg v. Mitchell (“Ellsberg I”),
In the course of discovery (pursuant to which Mitchell and the defendant agencies were required to acknowledge all wiretaps whose acknowledgement was not precluded by the government’s invocation of the state secrets privilege,
see Ellsberg I,
Despite plaintiffs’ pending discovery requests, the District Court granted summary judgment to defendants Rogers and Rowley on the basis of'plaintiffs’ failure to allege that they engaged in any illegal activity, and to defendants Laird and Helms for plaintiffs’ failure to allege that they were personally involved in the interception, use, or disclosure of any interception of plaintiffs’ communications. Ellsberg v. Mitchell, Civ. No. 1879-72 (D.D.C. Dec. 23, 1982) (Mem.Order), amended by Ellsberg v. Mitchell, Civ. No. 1879-72 (D.D.C. Feb. 1, 1983) (Order). In a separate order, the District Court also dismissed Russo’s suit entirely because he was not overheard on any nonprivileged wiretap. (D.D.C. Dec. 23, 1982) (Order). Later, also despite Young’s pending discovery motions, the District Court granted summary judgment to Mitchell on qualified immunity grounds against Young, finding that the “objective record thus establishes a valid [national security] rationale for the surveillance.” Ellsberg v. Mitchell, Civ. No. 1879-72, slip op. at 4 (D.D.C. July 22,1983) (Mem.Order). Plaintiffs appeal both orders. 1 We address them in reverse order.
*207 II
In granting summary judgment to Mitchell on qualified immunity grounds, the District Court properly reasoned that
“Harlow [v. Fitzgerald,
Defendants have alleged sufficient objective facts to place the wiretap of the Los Angeles Chapter of the Black Panther Party (which intercepted all four conversations at issue here) in a rational national security context. We so held in a previous challenge to the legality of the same wiretap.
Sinclair v. Kleindienst,
Even after considerable document discovery, plaintiffs can point to no objective facts that suggest a conclusion contrary to
Sinclair.
Instead, based on indicia of Mitchell’s “law enforcement philosophy,” Brief for Appellants at 29, and a catalogue of allegedly illegal
FBI
activity (entirely unrelated to the challenged wiretap),
id.
at 22-29, they urge us to find that Mitchell’s assertion of a national security purpose was pretextual. As we have said, such a subjective inquiry is not permitted.
See Halperin II,
Ill
Plaintiffs challenge the District Court’s grant of summary judgment in favor of Rowley, Rogers, Laird, and Helms, and its dismissal of Russo’s suit, on the ground that a genuine issue exists as to the truth of the government’s denial that plaintiffs were subject to other, non-privileged wiretaps that the government has concealed. Brief for Appellants at 9. The mere denial of a denial, however, does not suffice to create a genuine issue of fact for purposes of Fed.R.Civ.P. 56(c). Plaintiffs alleged no concrete facts that would sustain a finding that such nonprivileged interceptions existed. Plaintiffs argue, in essence, that the government’s “prolonged history of fraudulent misrepresentation” regarding its wiretapping activities and other prosecutorial misconduct could convince a jury that federal officials are in the “habit” of concealing such wiretaps from courts and are now behaving pursuant to that “habit.” Brief for Appellants at 31 (citing Fed.R.Evid. 406 (“Habit; Routine Practice”)); see also id. at 31-43. Further, each plaintiff enumerates a list of alleged governmental illegalities demonstrating official interest in him during and after the Pentagon Papers investigation and trial. Id. at 30, 44-45. For example, Russo alleges that he was subject to unspecified assassination attempts and “death threats from government connected sources.” Id. at 45. Young alleges that he could not locate some of his office files for several months, *208 and that his car was once unjustifiedly towed, and when he claimed it, local police took two hours to locate a briefcase he had left in it — from which he infers that the FBI both burglarized his office and copied documents in his briefcase — from which he urges us to infer that there must have been a wiretap as well. Id. at 30.
We decline to license any plaintiff to embark on a fishing expedition in government waters on the basis of such speculation. Cf

The judgments of the District Court are
Affirmed.
Notes
. A seven-line paragraph in plaintiffs’ brief, without citation to any authority, challenges the District Court’s order of June 10, 1982, Brief for Appellants at 45 — which the brief erroneously refers to elsewhere as “[t]he order of May 28, 1982,”
id.
at 3 — dismissing defendants Walters, Ingersoll, Aeree, Kleindienst, and Gray. However, plaintiffs failed to file a notice of appeal of that order,
see
Notice of Appeal (listing only orders of Dec. 23, 1982 and July 27, 1983), made no reference to the issue in their statement of issues presented, and declined to respond to defendants' assertion that such omissions constituted a waiver of appeal as to that order. Accordingly, that ground of error has been waived.
See
Fed.R.App.P. 3(a), 28(a);
Carducci v. Regan,
. Plaintiffs have not addressed on appeal, and are assumed to have abandoned, the claim that defendants violated any clearly established fourth amendment reasonableness requirements.
