Which of the following best describes the purpose of a grand jury?

The primary purpose of a grand jury is to assess evidence before trial. A grand jury is convened to evaluate whether there is sufficient evidence to bring criminal charges against a suspect. During this process, the grand jury reviews evidence presented by the prosecution, hears testimonies, and considers whether there is probable cause to believe that a crime has been committed and that the accused individual is likely responsible.

This function is critical in the criminal justice system as it acts as a safeguard against unfounded charges, ensuring that individuals are not brought to trial without sufficient evidence. Unlike a trial jury, which determines guilt or innocence, a grand jury does not decide the outcome of a case; it simply assesses whether there is enough evidence to proceed with charges. This distinction is important, as it clarifies the role of a grand jury in the legal process.
