SCOTUS may use the same constitution but that has nothing to do with it. It’s the interpretation of it that’s important, and why everyone wants “their guy” doing the interpreting. And I for one would much rather NOT have the judges come from the general public. Law schools don’t guard against unequal justice. If I’m not mistaken there are blatantly Christian law schools. Gee if the law is blind, why would these types of law schools even exist, or be allowed to exist? Because of the myth of equal justice. Similarly, I would much rather have juries be experts trained in logical reasoning, psychology, law obviously, etc. It wouldn’t be a perfect system of course, but it couldn’t get any worse than it is now.
