It has been confirmed that the DEA has allowed the Sinaloa Cartel, the largest, most deadly cartel in Mexico to smuggle drugs into the United States for 12 years - from 2000 - 2012. The Sinaloa Cartel supplies 80% of the drugs entering through Chicago and supplies every major city in the US with narcotics. US officials have also provided the Sinaloa Cartel high powered rifles and automatic weapons.
Reputable news agency in Mexico, El Universal, has published court documents that verify of this deal the DEA has made with the Sinaloa Cartel. The cartel has been allowed to smuggle drugs with impunity while providing intel on rival cartels, helping agents make record busts, and dupe the American public into believing they were actually doing their job preventing the flow of narcotics.
