The Grand Jury protects people against unfounded prosecution.  On the other hand, no felony case in Alabama can be tried without an indictment returned by a grand jury.

The following is the law concerning the secrecy of the proceedings:

§ 12-16-214. Legislative findings;  desirability of secrecy.

    The Legislature hereby finds, declares and determines that it is essential to the fair and impartial administration of justice that all grand jury proceedings be secret and that the secrecy of such proceedings remain inviolate.  The provisions of this division are to be construed for the accomplishment of this purpose and to promote the following:

    (1) That grand juries have the utmost freedom in their discussions, deliberations, considerations, debates, opinions and votes without fear or apprehension that the same may be subsequently disclosed, or that they may be subject to outside pressure or influence or injury in their person or property as a result thereof.
    (2) That those persons who have information or knowledge with respect to the commission of crimes or criminal acts be encouraged to testify freely and truthfully before an appropriate grand jury without fear or apprehension that their testimony may be subsequently disclosed, or that they may be subject to injury in their person or property as a result thereof.
    (3) That those persons who have committed criminal acts or whose indictment may be contemplated not escape or flee from the due administration of justice.
    (4) That those persons falsely accused of criminal acts are not subject to public scrutiny or display and their otherwise good names and reputations are left intact.
