The world has watched stunned at the bloodshed in Mexico. Thirty thousand murdered since 2006; police chiefs shot within hours of taking office; mass graves comparable to those of civil wars; car bombs shattering storefronts; headless corpses heaped in town squares. The United States throws Black Hawk helicopters and drug agents at the problem. But in secret, Washington is confused and divided about what to do. "Who are these mysterious figures tearing Mexico apart?" they wonder.
