The same reason every politician and government will never release them, because they are trying to protect themselves or someone else. As long as money and power remain the only things politicians care about this will never get released. And I find it absolutely infuriating that these people will always prioritize reputations over the literal r*ping of children. There are literally hundreds, if not thousands, of people just blatantly getting away with it because apparently every single elite is in on it.
