But the decision sends a message that cartels will be allowed to use violence to get their way. The Mexican security forces fumbled the operation from the start, arresting a top Sinaloa cartel suspect without enough backup to secure the area. And President López Obrador needs to forge a coherent strategy that provides a basic protection for citizens while tackling the deeper problems behind the violence.
Mr. López Obrador won his election last year thanks in part to his calls to end decades of corruption and uplift the poor. He rightly railed against the bloodshed and poverty that make people flee their homes, saying Mexico yearned for peace. Yet almost a year into office, homicide rates continue at record levels of more than 3,000 a month, while there are horrific incidents like gunmen ambushing and killing 13 police officers in the state of Michoacan last week.
I have been one of many voices criticizing the war on drugs and its catastrophic effects on Mexico. But the answer is not to give in to drug cartels, who can hold a major city and its residents under siege. The idea of drug policy reform, legalizing some drugs and providing better treatment for addicts, is to reduce the resources going to cartels and stop their rule of terror.
The problem in Mexico over the past decade is not only that the government has cracked down on traffickers by burning opium and marijuana fields. It is also that the cartels have used their billions to build paramilitary forces that lay waste to chunks of the country. It is not just a war on drugs but also a war financed by drugs. And that war does not stop even if the government is not attacking them.
Mr. López Obrador rightly points out that he inherited this problem. Reporting here since 2001, I have covered many dark days of this conflict: the massacre of 72 migrants; the disappearance of 43 students; cartel gunmen shooting down a military helicopter; a mass grave with more than 250 skulls. Yet that does not excuse him from the need to confront this humanitarian crisis.
