Sinaloa Cartel

The Sinaloa Cartel, often described as the largest and most powerful drug trafficking organization in the Western Hemisphere, is an alliance of some of Mexico's top capos. The coalition's members operate in concert to protect themselves, relying on connections at the highest levels and corrupting portions of the federal police and military to maintain the upper hand against rivals.
