A good faith answer to the question; classification hinges on damage done to the United States if it is released. So for example, a law might constraint or enforce the usage of a capability against an enemy, and this, of course would hang on some sort of spectrum also probably defined in law or in an agency interpretation. The agency interpretation is also probably classified and so as you start applying that spectrum, you enter gray areas and niches, and extremes, and so you have to ask a lawyer to disambiguate. And so this lawyer's interpretation is now the fulcrum on which employment of classified US capabilities is based. So therefore, teleologically this lawyer's interpretation has to be classified because it all goes back to whether public knowledge of this capability will damage the United States interest. if you know what the lawyer's interpretation is then you know the spectrum if you know the spectrum then you know the capability then you can damage the United States.
