Mississippi Constitution Art. 3, § 26

In all criminal prosecutions the accused shall have a right to be heard by himself or counsel, or both, to demand the nature and cause of the accusation, to be confronted by the witnesses against him, to have compulsory process for obtaining witnesses in his favor, and, in all prosecutions by indictment or information, a speedy and public trial by an impartial jury of the county where the offense was committed; and he shall not be compelled to give evidence against himself; but in prosecutions for rape, adultery, fornication, sodomy or crime against nature the court may, in its discretion, exclude from the courtroom all persons except such as are necessary in the conduct of the trial. Notwithstanding any other provisions of this Constitution, the Legislature may enact laws establishing a state grand jury with the authority to return indictments regardless of the county where the crime was committed. The subject matter jurisdiction of a state grand jury is limited to criminal violations of the Mississippi Uniform Controlled Substances Law or any other crime involving narcotics, dangerous drugs or controlled substances, or any crime arising out of or in connection with a violation of the Mississippi Uniform Controlled Substances Law or a crime involving narcotics, dangerous drugs or controlled substances if the crime occurs within more than one (1) circuit court district of the state or transpires or has significance in more than one (1) circuit court district of the state. The venue for the trial of indictments returned by a state grand jury shall be as prescribed by general law.
