You almost perfectly illustrate my point.
You don't want an 'audit' in the sense that anyone else comprehends the word - those are conducted regularly.
What you seem to want is someone to tell you that all of your misconceptions about the Fed were right all along but you can't even figure out who that would be or how they would come to that conclusion.
The word “seem” in your post illustrates precisely what you don’t know. And in this case, what you don’t know is of great magnitude.
Given the manner in which the Fed has presented itself and the way it conducts its business, there is no reasonable path to deem it an honest, or an honorable, enterprise.
