There has been a lot of attention paid to the role of US guns exacerbating the violence in Mexico. On September 14 2004 the assault-weapon ban expired and as you can see from the charts this program generates, there was an increase in the number of homicides and homicides with firearm. The big problem in trying to ascertain causality is that there were two confounding variables: La Barbie, working for the Sinaloa Cartel, was trying to take over the drug trafficking route of Nuevo Laredo, and the leader of the Sinaloa Cartel ended his alliance with the Juarez Cartel by killing Rodolfo Carrillo Fuentes, brother of the leader of the Juarez Cartel.
I used a zero-inflated Poisson regression model predicting the homicides by firearm count with and without a breakpoint. The model with a breakpoint occuring at the same time as the assault weapons ban proved superior.
La Barbie and Nuevo Laredo
In September 2004, he bought a full-page ad in the Monterrey newspaper El Norte and in an open letter declared that he was merely a businessman. He asked President Vicente Fox for justice and said he had left Nuevo Laredo because police there kept pressing him for bribes.
End of the partnership between the Sinaloa and Juarez Cartels
En él iban Rodolfo Carrillo Fuentes y su esposa; habían sido ejecutados por un comando en el estacionamiento del centro comercial Cinépolis en Culiacán, el 11 de septiembre de 2004.
El encargado de la operación que acabó con la vida del Niño de Oro —hermano del fallecido Señor de los Cielos, Amado Carrillo—, su mujer y seis personas más —entre ellas un lavacoches— era un oficial de infantería desertor del Ejército, quien a partir de esa fecha se volvió célebre en el mundo de los sicarios por discreto y eficaz y por haber realizado el ataque con el que su jefe, Joaquín El Chapo Guzmán, reventó su relación con los Carrillo.
