Mexican police detained a minor accused of working as a gunman for a drug trafficking organization after shocking videos and photos surfaced online of fresh-faced boys mugging for the camera with guns and corpses. One video, briefly posted on YouTube, showed a youth, apparently in his teens, confessing to working for a branch of the Beltran Leyva organization. "When we don't find the rivals, we kill innocent people, maybe a construction worker or a taxi driver," the youth said.
