The Jury system is very specific to the US 'tradition' (It reminds me the great movie "12 angry men"), we don't have a similar system in France (where it is one or several judges depending on the case who make the final decision).

Beyond technology and AI, one key issue for me is that the amount of money one can put on the table to defend oneself and hire good lawyers will have a real impact on the outcome of any judgement. What is true, what is right should not depend on the money.
