Did he or did he not? That is the question ... US Supreme Court Justice Anthony M. Kennedy presided over a mock trial of Hamlet, the Prince of Denmark, who was accused of murder some 400 years ago:
It gave noted Los Angeles attorneys an opportunity to argue for and against the proposition that Hamlet was suffering from a mental disease when he stabbed Polonius, the adviser to the king in the classic Shakespeare play.
After 20 minutes of deliberations, 10 jurors found him sane and two found him insane.
