If it’s allegations and you didn’t see it, how will you know that’s so?
The problem is that I don’t see it as relevant.
The person is now dead. Arguing his intent regarding his verdict is the equivalent of arguing the intent of the voter that created a hanging chad on their voter card.
Unless the guy comes forward and said, “I found for guilty becuase I hate black people and he is black”, there is nothing here to argue. And it doesn’t help that every other juror also found the defendant guilty. It’s not like we’re trying to turn a single holdout. The opposite is true. They are trying to nullify a verdict on a technicality, and a darned weak one.
