If they didn’t predict this kind of thing happening in their market then they are incredibly stupid. It’s an unregulated “market” where anyone can place a prediction on an outcome. The only limitation is certain types bets aren’t allowed, like betting on someone life. And I’m not sure how strictly that’s enforced.

Unknown, hey? Hmm, whoever it was, must be an incredibly intelligent mind. We’ll never be able to guess the people responsible. Oh well, close the case and let’s forget that this ever even happened… /s
