Inside the town, they say, crime is now down almost to zero and most residents seem to feel safe. In recent days, however, people from nearby communities have taken several federal police officers captive, demanding that the newly instated forest patrols be canceled so that they can continue their logging activities. (The officers have since been released.) It is unclear if the hostage-takers were illegal loggers, but tensions are flaring in Cherán as the rest of the country looks on with concern.

Last November, in a court appeal, Cherán acquired a degree of autonomy from the Mexican government; the town still receives federal and state money, and its people must pay taxes, but they are allowed to govern themselves under a legal framework called “uses and customs” that has been granted to some indigenous communities.

Legal experts and academics say that Cherán is the first community to be granted this right as a result of a conflict over natural resources with one of the country’s increasingly powerful criminal syndicates.

The residents’ actions have ignited a regional spark of do-it-yourself justice. In nearby Opopeo, residents have organized community patrols and created an alert system using church bells. In Santa Clara del Cobre, disgruntled townspeople kidnapped their police force for several days last February, suspecting it of having abducted and “disappeared” a local man accused of rape.

Still, the neighboring communities have not gone as far as Cherán. “If we do that here, we would need someone to take the lead, and if they did, they’ll kill him,” said Noe Pamatz, 64, a former member of the civilian security organization in Opopeo. He quit last month after its leader was found murdered.

Cherán’s residents say they were inspired to push for autonomy by some notable precedents. In 1994, Subcommander Marcos, the leader of the Zapatista rebels, staged an uprising in the southern Mexican state of Chiapas, demanding better treatment for the indigenous communities there, placing the issue on the national political agenda.
