”In effect, McCulloch staged a pre-trial trial in order to vindicate his personal view of Wilson�s innocence. But grand juries simply aren�t the proper forum for holding a trial. The most obvious reason is that they�re not adversarial settings. The prosecutor gets to present his or her view, but there�s no one to present the opposing view�a rather key feature of the criminal justice system. This isn�t a problem when the prosecutor believes the defendant is guilty, since the result is an actual trial. But when the prosecutor stage-manages a grand jury into affirming his view of the defendant�s innocence, that�s it. That�s the only trial we get.”
