I've served on a Grand Jury for 18 weeks once and while it is true that the Prosecutor has a great amount of leverage to try and swing the GJ, it is not that easy. When you have twenty people in a room with the ability to ask witnesses any question they want it sifts through the B.S. pretty quickly. Also, the GJ can ask anyone to come in and testify and the Prosecutor has to allow it.
Good points, thanks for patiently answering my questions and concerns. Now, I wish the MSM didn't change the word "indicted" to be a synonym of "guilty".
