Mimicking the tactics of Al Qaeda, cartels capture rival gang members, force them to confess on camera and place the video of their execution on the internet. But it's not only gang members being killed in this way. Musicians are being increasingly targeted. Since the revolution, bandits have paid to have songs composed about their exploits. But; "if a gang employs a musician and then another gang employs him, the musician becomes the enemy of the first gang", explains Father Esteban. Unfortunately, most of the time, musicians "don't know who the client is", until it's too late.
