Indictments are just that. There is a group of Federal prosecutors that review the criminal charges, look at the details, present their findings and then, only then when all the facts etc. are poured over, requestioned etc., do they pass it before a grand jury that listens to the prosecutor and witnesses, and then votes in secret on whether they believe that enough evidence exists to charge the person The reason for a SEALED indictment, is to stop the subject from fleeing. They’ll never know, until they are arrested, if they will be indicted. I believe there were something like 460 prosecutors that work on the Durham team.
