This shows a greater dilemma: we don’t want a caste of legal experts making fundamental decisions for an individuals life, but the alternative of getting a jury consisting of the average population who lack sufficient education also doesn’t lead to an outcome one would want when on trial. I wonder if there is a middle ground solution where the jury decides on parts of a trial independently without knowledge of other parts, e.g. only on admitting a piece of evidence.
