"Move the bright line to a point where no one has discretion, that is the solution."
What do you mean by that?
My understanding is that the only lawful solution is that actions are only derived from consent of the governed with a valid cause of action and that liability be explicitly defined and held to account equally for the accuser and the accused. This is the only lawful path I can see possible within the logic of law. All other procedures I have examined violate a law in the process of "enforcing the law".
