I am not a severe critic of the grand jury system, and it does serve a good purpose. However, when people are being indicted on flimsy evidence, the system's fairness needs to be questioned and one wonders whether it's time to place restrictions on it.
One other disturbing question I have read on the various threads is similar to this: "In how many other jurisdictions in this nation do they have runaway District Attorneys who use the grand jury system to persecute instead of prosecute?"
