Criminal organizations have an increasingly diversified and complex business portfolio. From their traditional activities—production, trafficking, and marketing of narcotics—they have expanded into fuel smuggling, transportation, extortion, kidnapping, private security, the construction industry, and a long and imaginative list of other activities. Organized crime was and is a very important power center in Mexico, which was already conveniently fragmented. Within this criminal framework, which is not monolithic, there is a constellation of organizations that compete with each other, fighting ruthlessly for business, where the only law is the one each imposes in its own realm, because that is the only way to survive.
