The Constitution creates an independent Grand Jury entitled to make its own “Presentments” with or without the approval of a Prosecutor.

At common law,a grand jury could freely "investigate..on[the]suspicion that the law[was] being violated...In light of the historic independence of the grand jury,the perfidy..in limiting the institution..can only be seen as willful subversion of well-settled law.”
“A presentment is a grand jury communication to the public concerning the grand jury's investigation. It has traditionally been an avenue for expressing grievances of the people against government.”
