From what I have read it is illegal in Missouri to release the voting record of the Grand Jurors.
Facts About the Ferguson Grand Jury Decision
"Robert McCullough, the St. Louis County prosecutor, explicitly stated that he would not disclose whether the grand jury was unanimous. Under Missouri State Code § 540.260, nine of the twelve jurors need to agree in order to indict someone for a crime. Since there was no indictment, all we know is that there were not nine votes to indict Darren Wilson on any given charge. Indeed, there could have been eight votes to indict him on one or more of the charges. Or the decision not to indict could have been unanimous. But we don't know. And given that Missouri State Code § 540.310 prohibits grand jurors from disclosing any individual juror's vote, we likely never will.
Could have said this in one breath, and “made the characterization” in another one.
