But, this is simply not the sort of manipulation to which the panel referred in Lieberman . In a related vein, we likewise reject the appellants' assertion that the government violated the Jencks Act by parading law enforcement officers rather than percipient witnesses before the grand jury. At this juncture the court directed the prosecutors to disclose the summary prepared by a government attorney for the use of the officer who appeared before the grand jury. The exception relates to count 15, as to which Houlihan offers a wider-ranging sufficiency challenge. We address that challenge separately.
Further examples are unnecessary.
It suffices to say that extensive evidence pointed to the conclusion that Fitzgerald and Houlihan jointly orchestrated both Sargent's slaying and Sweeney's travails. Indeed, when it was pointed out that a grand jury witness had testified otherwise, the government protested that the witness had made a mistake. See supra note 19. The grand jury testimony was not admitted at the trial. This is a salutary practice, and we commend it generally to trial courts confronted with analogous situations.
