Inside the Real Narcos was a pretty entertaining documentary where the guy actually meets with the gangsters and mafia down there to talk about how they made it big in the criminal underworld. A pretty fantastic watch if you're into that sort of thing.
At one point, they went to a crime scene where the cartel murdered someone and left their body in the middle of the road to leave a message. They showed the torso with all the limbs and head chopped off. The forensic guys laid out all 4 arms and legs and head for photos and it wasn't censored. Pretty gruesome stuff
