FBI Director James Comey, a former federal prosecutor, violated DOJ policy via his unprecedented announcement that "no reasonable prosecutor" would indict Hillary Clinton for using a private email system. But he provided the GOP with a decent video clip by calling the Democratic nominee "extremely careless" Though he spared Clinton the worst news - indictment, of which the likelihood was always zero, he did intervene in an extraordinary way in a presidential election.
Little noticed is the unprecedented and unauthorized character of his statement - issued he says without consulting or informing his boss the Attorney General of the United States. To my knowledge no such extensive statement has ever been issued by an FBI Director or a federal prosecutor. It obviously violates Justice Department policy as described below. - gwc
