The Sinaloa Cartel
The Sinaloas are considered by the U.S. intelligence community to be the "most powerful drug trafficking organization in the world." They operate in nearly every Mexican state and Zambada Niebla, a former Sinaloa member, said the cartel was given permission by the DEA to smuggle cocaine into the U.S. for years. The Sinola and DEA exchange information on cartels rival to the Sinola. By helping the DEA make arrests, the Sinaloa looks like the "good" cartel... while having its rivals eliminated for them the old fashioned way.
