To me, the Zetas are sort of the ISIS of the Mexican drug wars, they started the more brutal acts apparently and are like the devil on earth. And then again, if one sees the government siding with one Cartel, it can be the thing that breeds something like the Zetas. But the Zetas who are against Chapo’s empire of course, can’t be forgiven for horrors such as kidnappings and murder, they are probably involved in moving people across the border too. Complex situation, I heard some movie came out “Cartel land” and it talks about the self-defense groups (Auto defensas, Vigilantes to some) who defend with a measure of success, their own cities since the Mexican government and local police don’t do the job. What a mess.
