Grand Jurys are a way for the goverment to charge anyone they want to of a crime, do you people realize that any one of us could easily be inicted of whatever crime they want to. It is serious. It is a powerfull political tool.
They also use them to clear goverment officials of crimes. Even murder in cases like Fouad Kaady.
We should go back to the Perry Mason days (all of those shows were not trials but preliminary hearings) of preminilary trials and public inquests.
