Having served on a grand jury, one of the first things we did was delegate the management of documents (including subpoenas) to the court staff. We didn't issue our own subpoenas; that would have been thousands of documents we didn't have the time to manage. > Grand juries historically result in a 95%+ chance of indictment so this isn't a fishing expedition. There were cases presented to us which did not result in any indictment vote as new information was discovered or persons involved made deals with the prosecutors. The prosecutors didn't have us vote on things they weren't sure about, but that doesn't mean they never made mistakes.
