Prosecutors’ practice of avoiding searches in their own cases

Prosecutors’ practice of avoiding searches in their own cases is a procedural safeguard against a prosecutor becoming an essential witness in the very case he is responsible for presenting. In Andrew Barber’s grand-jury examination, the rule explains why he did not join the search for the murder weapon—but its professional logic cannot erase the personal act at the center of the questioning: Andrew had already disposed of Jacob Barber’s knife.

The Rule and Its Rationale

Andrew describes the practice as standard prosecutorial procedure. A prosecutor who takes part in a search risks finding evidence and becoming a necessary witness; if required to testify, he would have to give up the case. The same boundary applies more broadly to investigative work: a prosecutor waits elsewhere while a warrant is executed and observes an interrogation rather than conducting it himself. Andrew presents this as a lesson in professional roles, one he says he had once taught Neal Logiudice.

Its Application to the Knife Search

During questioning, Logiudice suggests that Andrew stayed away because the search was futile: the knife investigators sought had already been found in Jacob’s dresser and Andrew had dumped it. Andrew rejects that account. He says he knew the knife in the dresser was not the murder weapon and insists there was no doubt in his mind. Asked whether his absence was for technical reasons, he answers by invoking the rule against prosecutors participating in their own searches.

Procedure and Personal Responsibility

The exchange makes the rule’s limits as revealing as its purpose. Andrew says no one wanted the search to succeed more than he did, because finding the actual weapon would have established his son’s innocence. Yet he also admits that he disposed of Jacob’s knife, explaining that he believed Jacob was innocent and that it was the wrong knife. His account therefore sets a professional boundary beside a deeply personal intervention: the rule explains why he stayed out of the search, but does not undo what he had done before it.

Significance

The practice marks a distinction between prosecutorial responsibility and investigative participation, but the case strains that distinction because Andrew is both a prosecutor and Jacob’s father. In the grand-jury exchange, the rule functions as a concrete explanation of why he did not search, not as a resolution of the larger question of his judgment. Its emphasis on avoiding the witness stand also sharpens the irony: Andrew’s choices have made him a witness in the investigation of his own conduct.
