…the grand jury under our Constitution does not belong to any of the three branches of government, but instead to We the People. As a result, the citizenry are empowered to empanel grand juries, indict, try, convict and mete out sentences for those accused of crimes.
... the grand jury ‘can investigate merely on suspicion that the law is being violated, or even because it wants assurance that it is not.’ It need not identify the offender it suspects, or even “the precise nature of the offense” it is investigating.
The grand jury requires no authorization from its constituting court to initiate an investigation, nor does the prosecutor require leave of court to seek a grand jury indictment.
