You don't want to waste the court's time or jurors' time trying cases that should have been settled or dismissed.
There are types of criminal cases that do transcend the courtroom, and this is one of them.
I think prospective jurors and their families take that obligation very seriously, ... But that doesn't prevent some friend from telling them what they saw. It seeps through no matter what you do.
If you see a consistently high rate like that, I think you have a systemic problem.
The bottom line is you want to try to ensure a fair trial by an impartial jury. Any time the public is exposed to a prior criminal record, as they have in this case, you have to worry about that.
This is going to be a full-contact.
