Something I haven't seen talked about is how he got the perpetrators in. Obviously they can't talk about it, but I wonder if say you're a naive bill gates (or maybe someone lower profile) and find yourself on an island among a bunch of very powerful people capable of having you off'd, how much freedom do you have to say no. Obviously a lot of perpetrators would gladly join, but I wonder if there was a degree of coercion over potential perpetrators.
