I don’t think we’ll ever hear another peep on that subject, if Holder and Nixon have their way, do you?
I suppose you are correct. I think the butchers have their fingers on the scales.
On your original question (I don’t practice in the criminal defense area) could it be that by showing the Grand Jury everything the defense will get all evidence if there are charges preferred? In other words, the defense will get a total heads up on all possible evidence. There would be no concealment, or Perry Mason moments.
Of course the federal busybodies are not investigating state law violations.
