For all the talks about the inhuman violence of the northern cartels - Zetas and Gulf - I think the two most horrific showcases of cartel violence I've seen yet didn't take place in that region. That infamous video where they try to behead some guy, who has got his hands cut off and his faced peeled, with a box cutter while Sweet Child O' Mine and Funky Town are playing in the background took place somewhere in Sinaloa (not sure if it were the Sinaloa cartel doing this). And that one where a policeman is beheaded after which his son gets skinned and disemboweled alive was somewhere in Michoacan (done by some vigilante group Los Viagras or something like that). Truly new standards for brutality have been set over there. Horrible.
