It is illegal to make that information known, and the question was specifically asked at the press conference.
The prosecutor is a Dem. However, his father was in law enforcement, and was killed responding to a call involving a black suspect. That lead to some fears by him that if he doesn’t indict, it will be seen as bias, hence the decision to rather go the a grand jury to remove any doubts as to his motives.
Grand jury members are selected before the cases are assigned to them, so it was a random assignment. There is no jury selection process like there would be for a trial.
It all adds up to the fact that this process was as legal, transparent, and thorough as could be, with no opportunities to point fingers at the process or the prosecutor.
In the end it boils down to the same difference as always, for liberals, emotion trumps fact.
It was stated from the start that this GJ would be getting all available evidence as it was collected so the No Bill is actually credible.
Of course it wasn’t the “correct” decision so now they’re trying to trash its work and that of the Prosecutor. So typical of the lefties.
