Not directly related, but I've come to really appreciate the idea that a drug cartel is the ultimate example of a conspiracy, because not does it fit the definition really well, but it demonstrates what one actually looks like. There's no shadowy boardroom of hooded figures meeting in some underground bunker, but rather playboys loudly broadcasting their wealth & power with only the barest minimum of deniability maintained at the legal perspective, with the general populace fully aware but powerless to really do anything about it. And yet, it still is a multi-national network of coordinated logistics and execution for multiple tons of product that both the official powers & general public would really prefer to not to be there.
