Now you can, courtesy of OverLawyered.com, which reports on (and links to) a Cato Institute report re: "[Few Americans] have any idea about what the grand jury is supposed to do and its day-to-day operation. That ignorance largely explains how some over-reaching prosecutors have been able to pervert the grand jury, whose original purpose was to check prosecutorial power, into an inquisitorial bulldozer that enhances the power of government and now runs roughshod over the constitutional rights of citizens." Kind of interesting, if you ask me.
