You are guilty until proven innocent. The laws you are supposed to follow were collected over time thousands of years ago in another culture, but you’re screwed because the laws can’t be amended, reviewed, or doubted. You were born guilty–deserving eternal torture and punishment for something you cannot control. The only way for you to be saved from this terrible pain and suffering is for the judge to kill an innocent person instead of the guilty one. But don’t worry, the innocent guy only stays dead for three days, so it’s only a really bad weekend.
You are innocent until proven guilty. The laws you have to follow are agreed upon by your local/state/federal governments instead of just one person; if there is confusion, there will be a final word on what’s okay or not okay to do. Revisions are also possible for the betterment of society. If falsely accused for a crime you did not commit, you can appeal to a higher court. You have a right to be judged by a jury of your peers. You cannot be prosecuted for thought crime. Punishments are not eternal, and only the criminals are punished for their own actions.
P.S. I admit, we all know the American justice system is a bit messy; but its ideals are still better than the theocratic alternative. Oh, and if you’re not American, I’m pretty sure your scenario would be very similar. That is, unless you’re from North Korea.
