Mexican Drug War

And the spillover continues: The bloody prohibition war that has claimed tens of thousands of lives has spread to the Lone Star state's agriculture, where drug traffickers are targeting farmers' livelihoods. Texas farmers and ranchers say confrontations with Mexican drug trafficking organizations are quietly adding up. Several growers and ranchers say their jobs started becoming more dangerous about two years ago.

Mexico has made an official request for more information about a secret U.S. government operation to allow smugglers to take nearly 1,800 guns into Mexico in an effort to track them to drug trafficking organizations. The operation, code-named "Fast and Furious," was run by the Bureau of Alcohol, Tobacco, and Firearms (ATF), in spite of objections from its own agents. Assault weapons and high-powered sniper rifles were among the guns smuggled in to Mexico over a period of 15 months. Some of the 1,765 weapons have since been linked to crime -- including the murder of a U.S. border patrol agent in December. Fewer than 800 of the guns have been recovered.

A shoot-out between rival drug trafficking organizations left 18 people dead in Mexico's Tamaulipas state, amid a surge in deadly drug prohibition violence. The state has been the scene of horrifying killings, including last August, when a mass grave containing the bodies of 72 people, believed to be Central American migrants, was found on a local ranch.

In the last few weeks, more than a dozen taxi drivers and passengers have been murdered in the resort city of Acapulco. A 2008 survey reported that 120 of the 200 taxi drivers in the city of Chetumal, Mexcio, reported to have been threatened with violence against their families if they refused to deliver drugs on behalf of the local drug trafficking organization.

Thousands of people have vanished without a trace – some caught up in prohibition violence, others for no reason anyone can fathom. Relatives remain in agonized limbo. The disappearances are a disturbing echo of a tactic employed by dictatorships in the so-called dirty wars that plagued parts of Latin America in the last half of the 20th century.

Police have tied the October beheading of a man in the Phoenix suburb of Chandler to a Mexican drug trafficking organization. "They stabbed him, we believe to death, and then severed his head. There was a lot of blood," Chandler police Sgt. Joe Favazzo said.

Hitmen are killing human rights workers across Ciudad Juárez -- the city in Mexico most affected by drug prohibition violence -- in brazen attacks that activists say authorities are unable and unwilling to halt.

Residents have closed more than 2,000 streets in Ciudad Juarez, the city in Mexico most affected by drug prohibition violence. About 200 families have been wiped out in 10 zones heavily affected by the drug prohibition war.
