No, I haven't shown any evidence at all that it's unusual in MO.
Because we have all just sat through months of news articles and commentary explaining how all of those things are not the normal way of conducting a Grand Jury.
I could provide links of District Attorneys and other Court officers stating as much, if I thought that would satisfy you. But I feel it will just devolve into arguing silly minutia.
If you want to believe that this GJ was conducted in a typical fashion, have it at. I think the people in this thread willing to have an honest discussion about the case know better.
What's the point - Did I or someone claim otherwise ?
Your opinion on how GJs should be conducted has nothing to do with the way GJ are actually conducted.
