True Statement Pertaining to the Grand Jury
The correct statement about the grand jury is that their purpose is to determine whether there is probable cause. Grand juries are composed of citizens and are tasked with deciding if sufficient evidence exists to prosecute someone for a felony. They do not issue guilty verdicts; that is the responsibility of a trial jury after a case goes to trial. Additionally, grand juries are not necessarily panels of legal experts, but rather laypersons who are called upon to evaluate evidence presented by the prosecution. While convening a second grand jury on the same matter is generally discouraged to avoid 'forum shopping,' there is no absolute rule against it under certain circumstances.
