I have seen it, in English, legitimately. Incredibly dark, important film. If not to the systemic corruption and sanctioned drug trafficking which is crucially relevant to current affairs in Mexico, then it is an important piece into the psychology of someone who explains his "work" in a tone you expect a teacher would explain their administrative responsibilities.

His description of early enticement into the trade, through training, through to various responsibilities and participation in conducting brutality of "enormous suffering" at the will of "el patron". This interview is not only a confession of a mass murderer it is a testament to how organised and how rooted the drug industry is in the Mexican economy and politics. An echo of a tragic history which ripples across south America over the decades.
