I am merely looking at the arguments they just made.. Feldman encourages the hold out to stay firm while Dusek encouraged a hold out to go with the majority. They apparently both agree that the best case scenario is a hung jury with a single holdout.
Or, another view is that both lawyers have enough experience to know they cannot predict what every member of every jury will do.
That no matter what else, don't assume you WON. Go for the minimum, the single holdout that will give you your win. SO, for Prosecution it is eliminate the holdout, for Defense it is get a holdout.
This would be true in every court case.
