Which of the following court members dominates the grand jury?

The prosecutor plays a dominant role in the functioning of a grand jury. The primary responsibility of the grand jury is to determine whether there is enough evidence to bring criminal charges against a suspect. The prosecutor is the central figure in this process, as they present evidence and witnesses to the grand jury and guide the proceedings.

Unlike a trial jury, which weighs the evidence to determine guilt or innocence, a grand jury operates in a more investigative capacity, and the prosecutor leads this inquiry. They prepare the case, submit evidence, and help jurors understand the legal standards. The absence of a judge's direct involvement in deliberations or the need for a defense attorney in this stage of the process further underscores the prosecutor's pivotal role in shaping the outcome of grand jury decisions.

Thus, the prosecutor’s authority and influence in the grand jury setting is fundamental, allowing them to effectively control the narrative and direction of the proceedings.
