Here is a full translation from a native Mexican:
Video starts
Torturer: "Look at how your son is, son of a bitch, just like the other one. Open your eyes, open your eyes (untranslatable Mexican slang word (Guey), means dumbass and used like dude is in English depending on context)"
Beating on cop with log starts
Torturer: "Open your eyes, (talking to the son).
Hold him up to watch. (to another cartel member)
You dumbass, what the fuck does your wife know? (to cop)"
Cop: "noting!"
Torturer: "And if I go get her?"
Cop: "nothing, she knows nothing…"
Torturer: "You know one thing (to camera), look Tecuan, I’m going to tell you one thing, son of a bitch, nobody messes with us son of a bitch. And I’ll tell you one thing, In order to come into the plaza it will cost you dearly, first the same thing will happen to you like this piece of shit, (beats cop again)
Come here and take their beating son of a bitch
I’m going to tell you, here we are “Los Viagra” (The Viagras, name of the cartel) and the shit is the shit, all of these grasshoppers that are being mules giving out information, fearing any dumbass, their bitch of a mother is going to take them.
(Slang Word for knife) literal translation: Iron old man (to another cartel member)
Open your eyes boy! (to cop’s son)
And if he closes his eyes fuck him up.(To other cartel members)"
Comences slicing into cop’s neck, son starts screaming
Torturer: "stand the fuck up! Look! (to cop’s son)
Tecuan (to camera), this is...(Cop’s son faints) Get up! (beats unconscious boy)…(slicing continues on cop) Get up.... I will wake you up! (Picks up boy.... Boy then wakes and screams again)"
