Mexico's slide into global guerrilla warfare took another baby step today as the regional paper, Cambio Sonora, shut itself down due to security threats from drug gangs. The paper had already stopped most of its investigative reporting into the drug industry, but that was insufficient (likely a correct decision since 7 journalists have been killed since October and the newspaper has suffered two grenade attacks). The breadth of this violence against the media and its apparent randomness (as opposed to selectivity) demonstrates conflicting motives and a loss of central control (which strongly indicates a shift in organization form).
Of course, you can still find narcocorridos, torture/death videos and other messaging from the gangs.
