What cases go before a grand jury?

Grand juries typically hear cases involving serious criminal offenses, such as felonies, to determine whether there is enough evidence to formally charge an individual. They review evidence presented by prosecutors, including witness testimonies and documents, without the presence of the defense. Common cases include drug trafficking, homicide, and organized crime. Grand jury proceedings are generally secretive, aiming to protect the reputations of those investigated if no charges are filed.
