Yes, they are hoping for an all black jury that thinks whitey deserves everything they can do to him.
Their chances are even better than that: all they need is ONE juror to vote for acquittal, and that’s a hung jury ... and, at worst, a chance for a more lenient plea bargain next negotiating session. Maybe, depending on the DA’s office, they wouldn’t even be re-tried, and just let go at that time.
It might take a lot of effort on the part of the court system (in Chicago!) to see that justice is done in this case.
