In Michoacán, three storage places of the Sabritas company, which makes potato chips, were burned down in three different places in the state. One does not need much imagination to see this as a case where "protection money" was likely not paid, or was deemed insufficient - one of the oldest mafia practices in the book, far predating the advent of drug trafficking. Hence, "mafia," not "drug cartels."
