Special to the Chronicle by Bernd Debusmann, Jr., who is currently studying for an MA in International Journalism at City University London. Prior to that, he lived and worked in his native Mexico, most of it as a full-time freelancer for Reuters TV, also contributing to Fox Latino. Earlier he worked as a reporter in New York City and as a freelance producer for the Reuters Latin American Television Desk in Washington DC, during which time he dealt with many drug trafficking stories. During 2010 and 2011 he authored the weekly Mexico Drug War Update published by this newsletter, available in our Mexican Drug War archive section.

At around 06:40 on the morning of Saturday, February 22^nd, Mexican marines and police officers arrested Sinaloa Cartel boss Joaquin "El Chapo" Guzman at a condominium in the Pacific resort town of Mazatlan. Without a doubt, Guzman is the most significant organized criminal captured or killed since the current Mexican drug war began in December 2006. But what effect will his capture have on the violence in Mexico and the flow of drugs to American consumers? Not much.

[image:1 align:left caption:true]Guzman was widely regarded as the world's most powerful drug trafficker, and his aggressive organization has been a significant contributor to the violence that has gripped Mexico in recent years. This is especially true in Tijuana and Ciudad Juarez, where the Sinaloa Cartel's bloody and drawn-out takeover of the access routes to the US drug market left thousands dead over the course of a three year orgy of violence.

Since his January 2001 escape from prison, Guzman turned into a mythic figure, Mexico's answer to Osama bin Laden. For much of his administration, former president Felipe Calderon was dogged by accusations that he was protecting Guzman, and ridiculed for not being able to find him. In February 2013, the Chicago Crime Commission named him "Public Enemy #1" for his role trafficking wholesale quantities of cocaine and heroin to the city.

Given his notoriety, Guzman's successful capture is a significant PR victory for the PRI administration of President Enrique Pena Nieto, as well as for the DEA and other American law enforcement agencies. But the victory may well prove much more symbolic than strategically meaningful.

Guzman's capture does not mean an end to the Sinaloa Cartel, a long-established and sophisticated organization whose tentacles spread across the world. The cartel is often referred to as "The Federation," of which Guzman was not the only leader. In his absence, much of the organization will likely come under the control of Ismael Zambada Garcia, aka "El Mayo," a capable and intelligent career drug trafficker considered by many to have been Guzman's equal. The organization can also count on the services of Juan Jose Esparragoza Moreno, aka "El Azul," a crafty former police officer well known for serving as a peacemaker between rival criminal organizations.

Another possibility is that Guzman may well be able to continue to exercise some control over the organization from inside prison, as he did the last time he was incarcerated. Mexico's prisons are notoriously corrupt, and many drug traffickers and criminals have been able to continue to direct the day-to-day operations of their organizations in relative comfort in posh cells.

Guzman's capture is very unlikely to have an effect on the overall level of violence in Mexico, and may actually lead to an increase in more bloodshed and mayhem if the Federation were to break up into rival factions fighting to fill the vacuum. Many Mexican narco-blogs are already theorizing that Guzman was given up by members of his own organization, perhaps even El Mayo himself.

This was the case after the 2009 killing of Arturo Beltran Leyva, which led violence to spike as his underlings fought amongst themselves to fill the void. It should also be noted that Beltran Leyva's organization was considered part of the Sinaloa Cartel until a violent split with Guzman in 2008, demonstrating the fickle and fluid nature of these organizations.

Another possibility is that -- sensing an opportunity -- Sinaloa Cartel rivals such as the notoriously violent Zetas will take advantage of the arrest and go on the offensive in Sinaloa's turf. This is not without precedent. In mid-2012, the Zetas, along with elements of the Beltran-Leyva organization and the Juarez Cartel, made a push into Sinaloa-controlled territory in mountains of the Sierra Madre.

By the American government's own admission, the Sinaloa Cartel has dozens -- if not hundreds -- of distribution cells across the US, as well as Europe. Additionally, the cartel is thought to have an organized logistical network across Central and South America. Guzman's arrest leaves these networks intact, and business will continue regardless of who is in charge.

That happened after the 1993 killing of Pablo Escobar in Colombia. Despite having eliminated the world's most wanted drug trafficker of the time and leaving the Medellin Cartel in tatters, the northbound flow of cocaine continued. His organization splintered into several smaller organizations, which, while being less capable of challenging the state, were more than up to the task of keeping business going at a steady pace.

Guzman was an immensely important drug trafficker with few equals and had the blood of thousands on his hands. His freedom had become an embarrassment to the Mexican government, and his eventual downfall was inevitable. But it is unlikely to have any significant impact on the flow of drugs from and through Mexico, or on the violence that continues to plague large swathes of the country.

As long as Mexican cartels can deliver the illegal commodities that American (and European) customers want, drug trafficking organizations will continue to exist. While there are very few drug traffickers currently of the same calibre as Guzman, as long as prohibition continues there will be ruthless, violent and intelligent individuals who want to profit from it. This means that there will always be a pool of people to replace men like Guzman. Only through sensible drug laws and demand reduction can these organizations be weakened and eventually driven out of business.
