The court system in America in real life work by having unexperienced people told of a situation and informed of all the details they need to know in order to make an unbiased decision. Why would u want a bank robber to decide if the shop lifter is innocent or guilty? I want a person who is not attached to the situation at all to be the person to make judgement on said situation. Note I did not say an uninformed person but an unattached/experienced person.
