At What Level Is Grand Jury Guaranteed Right

At what level is a grand jury a guaranteed right?

Answers:

When crimes are committed, law enforcement swings in action to nab the suspect and gather evidence. When evidence gathers, law enforcement turns it over to the local prosecuting attorney. In many state courts and federal courts, the prosecuting attorney presents this evidence to a grand jury. The grand jury decides if the evidence warrants an indictment and trial.
