Jose Ramos, security expert at the Colegio de la Frontera Norte in Tijuana, says such tips erode trust in the police, as people will always question whether a case was solved thanks to the help, or even complicity, of traffickers. “This is worrying,” says Mr. Ramos. “We are substituting the work that the state should do to identify alleged murderers and kidnappers.”
On Thursday, another man who appeared in a separate video confession was found murdered. In a video released shortly after Mario Angel Gonzalez Rodriguez was kidnapped in October, he says that his sister – Patricia Gonzalez, the former state prosecutor of Chihuahua – had worked for an offshoot of the Juarez Cartel. Ms. Gonzalez has denied the claim, saying her brother had spoken under duress. Police are reportedly investigating the allegations.
This tactic is used not only to incriminate rival gangs, but also to discredit the authorities, says Jorge Chabat, who studies the drug war at the Center for Research and Teaching in Economics in Mexico City.
