Information on how he got caught getting in the hands of criminals could be problematic. 'National security' isn't how I would have phrased that and I forget how they phrase it normally, 'means and methods' maybe? Also if it was just a list of names then it'd inevitably become a list of people whoever's in charge wants to get rid of, considering people have for the most part been trying to use Epstein's legacy for wish fulfillment by saying their name's on some magical list that most likely doesn't exist. Dude ran a bunch of somewhat legitimate businesses too, would surprise me little if they're all in the same contact book and the only copy of the list of which one's are pedophiles was in his head.
