What is the role of a grand jury?

A grand jury plays a crucial role in the legal process, primarily serving as an investigative body. It is responsible for evaluating evidence presented by the prosecution to determine whether there is enough probable cause to charge an individual with a crime. This process involves gathering information, hearing testimony from witnesses, and reviewing documents. The grand jury's function is to protect against unfounded criminal charges by ensuring that there is sufficient basis before an individual is formally accused.

While a grand jury does not determine guilt or innocence, it helps filter out cases that do not meet the necessary legal standards for prosecution. This function is distinct from that of a trial jury, which is tasked with deliberating on the evidence presented during a trial to reach a verdict. Therefore, the grand jury's investigative role is an essential part of the legal system, aimed at safeguarding individual rights while facilitating the prosecution of valid criminal cases.
