Mexican DTO's will not think twice to utilize the US and Mexican street gangs to maximize their effort in ensuring they remain the primary supplier of illicit drugs to the US.
Looking at the crime spree in the last few years in Mexico they have good reason to be suspect and be very concerned. The massacre of 16 students in cold blood in February of this year in Ciudad Juarez was possibly done to take out some of the "Double A" or "Artistas Asesinos." The mass killings last year in some of the rehab centers in Juarez have had ties to Barrio Azteca.
It has been rumored for some time that street gangs have allied with the big drug cartels, in the US and Mexico. They do this to distribute the drugs and in many cases to be the foot soldier of the big drug corporations.
The Barrio Azteca has had a strong relationship with the Juarez cartel while the “AA” have been rumored to support the Sinaloa cartel of El Chapo Guzman.
So we should not be surprised when Mexico apprehends sicarios and they find them to be from a street gang with a cartel connection. Americans are very concern about the “spillover” of violence and drugs in to US soil, and some even dread that perhaps someday the Mexican drug cartels will set up shop in the US as they do in Mexico.
They will be more discreet about it and more likely will use the street gangs to accomplish it. The street gangs are already in the streets and already have a working knowledge in the criminal enterprise, on a more grass root basis, but they still perform the same functions to a degree.
The truth be told, the big Mexican drug cartels already use the street gangs in Mexico and US, and will most likely use them more now that the heat is on to continue their huge profit from the huge drug consumer to the north. That is certainly guaranteed.
