>> anthony: every day, mexico wakes up to count the dead. they are, after all, left out to be seen. often with a helpful note, identifying who done what and, generally speaking, why. there is a language to the never-ending violence. a coded message in the twists and marks of the bodies. and valente rosas is one of the many documenting them for the press. this is what he does every night. rides around, waiting for a phone call, or a radio message, telling him that there's another one. so, who's buying drugs? who's selling drugs to who?
