NEW YORK (TheStreet) --When a notorious criminal like Sinaloa drug cartel chief Joaquin "El Chapo" Guzman is brought to justice, it's time to celebrate, right?
Maybe not so much if you read this Department of Homeland Security analysis of the impact of death or arrest of key drug traffickers.
"While the continued arrest or death of key DTO leadership may have long-term implications as to the control and viability of a specific DTO, there is no indication it will impact overall drug flows into the United States," it concluded, after studying drug seizure data across the southern U.S. border between from January 2009 to January 2010.
So the positive effect in terms of reducing the flows of drugs into the U.S. is zero. We didn't really need the Department of Homeland Security to tell us this. Would anyone really want to try and argue that the death of Colombian kingpin Pablo Escobar -- or any slightly less notorious drug lords since -- decreased the flow of drugs into the U.S.?
What's worse, it likely only increases the amount of violence over the short term as turf wars ensue to fill the power vacuum left behind following Guzman's capture.
Mexican President Enrique Pena Nieto seemed to grasp the futility of the drug war when he took office in 2012.
"He said we need to focus on citizen security which was a smart move," argued Sanho Tree, drug policy fellow at the Institute for Policy Studies, a Washington D.C.-based think tank.
"Focus on kidnapping, extortion -- these things where other criminal elements as well as drug traffickers have expanded -- and Sinaloa wasn't really into that as much as the others. Sinaloa as a cartel was actually less violent than the others, although they're perfectly deadly, so why go after Sinaloa? Simply because of volume? Many people argue that you go after the Zetas, the Templars, some of these other cartels that use violence as their one and only method of control, whereas Sinaloa's always been -- they'd much prefer to give you a bribe over a bullet. But if you don't take the bribe they'll definitely use the bullet."
Still, Tree argued, "If you're stuck with drug traffickers it seems to me that's the kind of drug traffickers you'd want. You can induce better behavior amongst these criminal elements by going after the most problematic ones."
While Mexico's drug war rages, north of the border the push to legalize marijuana continues.
Guzman's arrest attracted substantial attention in the U.S. in recent days. The Sinaloa Cartel had been designated a "Significant Foreign Narcotics Trafficker" by the U.S. Government.
