The unusual situation facing Robert Mueller does not justify a repeal of well-established traditions of confidentiality.
As the nation awaits the Mueller report, a return to first principles is in order. One relevant first principle was dramatically illustrated in the breach during the waning weeks of the 2016 presidential campaign. Then–FBI Director James Comey announced at a press conference that no criminal charges would be brought against Hillary Clinton. Comey didn’t stop there, however. In that press conference, which will continue to live in infamy, Comey sharply criticized the former secretary of state for her ill-considered conduct in housing a server in her private residence, only to receive official and—not infrequently—classified information.
The nation should have risen, as one, in righteous indignation in the aftermath of the Comey press conference. In a single misadventure, Comey both seized power that was not his—the power to seek an indictment, a prerogative that was entrusted to the attorney general—and then violated one of the fundamental principles of public prosecution: Thou shalt not drag a subject or target of the investigation through the mud via public criticism. Prosecutors either seek an indictment, or remain quiet.
