It probably doesn't answer your question, but I don't see the BATFE as an "organization". They are a law enforcement agency. They are supposed to enforce laws, as they are passed. I don't like to think of the director of a law enforcement agency as having policies. They have laws they are tasked with enforceing, so what would be a policy? Enforce laws, or don't enforce laws?
"It is the policy of this law enforcement agency to enforce "law A", but not enforce "law B". " ???
I would like to see a policy of direct answers, and clear cut interpretation of laws. For instance, what about a letter from an agent of the BATFE that says after registering a short barreled rifle, there is not further legal requirement to mark or engrave the reciever. Then, in the very next paragraph, outline the legal requirements for engraveing an SBR. To me that is very ambiguious, since it conflicts with itself.
