I mentioned several posts above that I did.
I wasn’t part of an investigative grand jury; those go one year for general investigations. That type of grand jury is probably what will hear evidence.
My service was once a week for six months and we listened to the evidence for anywhere from two to ten cases per session given by a US Asst. Attorney, and we either came back with indictments (meaning only that there was enough evidence for a trial) or we didn’t. Also, attorneys cannot ask us questions, but we can ask them and/or agent involved questions. We could subpoena a witness or ask to hear from others if we felt it was relevant. We don’t advise anyone; it’s a simple vote for indictment.
BTW, the panels were created by the computer, which spit out names in what appeared to be a random fashion. There was not a voir dire for any of the multiple panels created that day, including the investigative panels.
