nGrand jury proceedings are typically closed
to the public. The
prosecutor appears before the grand jury with a series of cases he has built against various defendants. Witnesses are called and physical evidence is presented. If the grand
jury believes that a
given case is substantial, it hands down an indictment, or true bill.
nIn the overwhelming majority of cases, grand juries hand down indictments against persons
as requested by
prosecutors, leading some to question the utility of the grand jury procedure as a means of guarding against arbitrary or unwarranted prosecution.
