MEXICO CITY — The most ruthless gang of drug-cartel hit men in Mexico are deserters from the army's elite. But the Zetas, as the ex-soldiers are known, may not be the only troops who abandoned their posts to work for the cartels.after reading this I wonder if America will be this way IF Amnesty passes Mexican hit men going after our eleted officals ???? Hope not_High vulnerability
A reluctance by soldiers to act as police may have played a role, some experts said. Of the 4,890 soldiers assigned to the federal police force to help combat traffickers during the 2000-06 administration of former President Vicente Fox, all but 10 deserted, said Gomez, citing Defense Secretariat figures.
"Many are scared," said retired Gen. Luis Garfias Magaña, noting that hundreds of soldiers have been killed in clashes with the cartels over the past decade. "Before, a few died combating guerrilla groups," he said. "Now, they're fighting a veritable war against the traffickers."

The danger has escalated under the seven-month administration of President Felipe Calderon, who has sent more than 25,000 troops and federal police to areas under siege by the traffickers. In the process, experts say, he has also made the soldiers vulnerable to the cartels' corrupting influence.

"It's part of the larger issue which the military has always feared," said Roderic Ai Camp, an expert on Mexico's armed forces at Claremont McKenna College in California.

"It exposes all those people who come in contact with the anti-trafficking mission to corruption."

Gomez said she believes that rival gangs were already using former soldiers to combat the Zetas. She pointed to a video aired on YouTube in March showing men with assault rifles and combat fatigues interrogating two captives, who identified themselves as Zetas. Soon after, another video appeared of unidentified captors torturing and decapitating a man with a "Z" painted on his stomach.

"You can tell by how they act," she said of the captors. "These aren't police. And they certainly aren't local ranch hands."
