I don’t see the problem. Though of course I am one of the rules lawyers in DnD. The rules exist clearly stated. If there becomes problems then the table should decide amongst themselves how to change said rule so it is no longer a problem. If a player does not like the change they can ask for a compromise or find a new table.
Without these clearly written rules you have what amounts to arguments like we had as children were we argue over if someone shot someone else in a cops and robbers chase.
This example fails because there are clear laws. Many many statutes (in fact I would argue at any point it requires a lawyer 7 years to specialize in a very narrow branch of the law) that specify and categorize what is illegal behavior. If a police officer arrests or tickets you, you have the chance to fight it in court. Were judge or jury decide on the case. You then have the right to appeal to a higher court, multiple times. This system works (or is supposed to, see below) because of the number of checks and balances that enforce impartiality.
Now cases do happen were there is clear evidence that the judge is biased and appeals are declined such as the recent Sullivan case. These should not be accepted however and the court of public opinion should and often does change rulings in clear cases of corruption such as the 50 year old lady in the capitol riot case.
If your not familiar with the case you can see a discussion here although Barnes is pretty worked up.
