Clarifications on the grand jury system...
The U.S. grand jury system is not a court. It is an empanelled jury of citizens that considers the prosecution's available case and then decides if there is enough evidence to issue an indictment/go to court for a criminal trial where another jury might render a verdict and punishment could be handed down. The reason grand jury records are private is because it is an investigatory step, where guilt-by-association could come into play if the parties being investigated were announced and a cloud placed over their reputations even if the grand jury ultimately makes the decision that the evidence is not sufficient to warrant an indictment.
