Mexico: Illusory Victories in Michoacan

Mexican officials said Dec. 18 they have arrested several major players in the drug cartels operating in the violence-plagued southwestern state of Michoacan. The arrests are part of Mexican President Felipe Calderon's effort to act on a campaign promise to aggressively target the cartels. Despite the dozens of arrests resulting from the operation, the sweep will result in only minimal long-term damage to the cartels.
