The United States and the European Union do want to have a rule of law, and that rule of law should be for a fair trial. And that fair trial needs to have an impartial jury.
I recently saw the movie about Ray Charles, and there's a scene where he falls down and the mother doesn't help him. She says, I don't want anyone to treat you like a cripple. I've fallen down before, and Molly will say, get up and just go.
