You can apply policy top-down. But actually the higher one rises the ranks the more it is about pure, immoral power play. This again leads to the best psychopaths being at the top, which again means policy won't exclude their main methods of action. So really, what do you want to do about it? You can't enforce policy bottom up. That's why someone is above you in the food chain.
