I would steer them from "conspiracy theory" to the term "organized crime." No reasonable person denies the existence nor the deep-penetrating influence of the various mafias of the world. They corrupt police officers, government officials, and judges. How do mafias go from minor-league bands of criminals to powerful mafias? Could there be a mafia of mafias that rule above them all? How likely is it that no powerful crime syndicate would desire to achieve that position?
