In NC, he is REQUIRED by law to tell the Grand Jury exculpatory information, which most of this sounds like.
Well, if that's really the case, then it explains why he avoided getting any (exculpatory evidence offered to him) and rushed in to get his indictments before any could be rammed down his lying throat.
Are you sure he's required to present exculpatory evidence? I have heard NC attorneys state on the talking head shows once or twice that it's not required, and that the GJ has the right to further investigate.
