I do not have magical powers that would cause the FBI (or any other component of the DOJ, come to that) which would cause them to act in morally positive ways by simply imagining "how it should be". If there is a "how it should be" when it comes to the DOJ, which seems very doubtful, there exist no humans on planet Earth who could implement it. Even more so, it would be impossible to know how to implement it without thoroughly and profoundly understanding the various failure modes. In other words, you're even doing the "examining the way the world should be" wrong.
