MEXICO CITY (AP) — The notoriously violent Jalisco cartel has responded to Mexico’s “hugs, not bullets” policy with a policy of its own: The cartel kidnapped several members of an elite police force in the state of Guanajuato, tortured them to obtain names and addresses of fellow officers and is now hunting down and killing police at their homes, on their days off, in front of their families.
The Zapatistas also do a good job of keeping cartels out, though I'm not sure how appealing Chiapas is to the cartels.
I think the cartels get all the territory they can; Chiapas is not appealing thanks to the Zapatistas.
