Mexico's drug war

In December of 2006, Mexico's new President Felipe Calderón declared war on the drug cartels, reversing earlier government passiveness. Since then, the government has made some gains, but at a heavy price - gun battles, assasinations, kidnappings, fights between rival cartels, and reprisals have resulted in over 9,500 deaths since December 2006 - over 5,300 killed last year alone. President Barack Obama recently announced extra agents were being deployed to the border and Secretary of State Hillary Clinton heads to Mexico today to pursue a broad diplomatic agenda - overshadowed now by spiraling drug violence and fears of greater cross-border spillover. Officials on both sides of the border are committed to stopping the violence, and stemming the flow of drugs heading north and guns and cash heading south. (34 photos total)

A farm canal is seen at sunrise March 12, 2009 near El Centro, California. El Centro is suffering the highest unemployment rate in the nation at 22.6 percent, nearly as high as rates during the Great Depression, with Latinos especially being hit hard. The people of the Imperial Valley, an important food producing region in the desert north of the U.S.-Mexico border and east of San Diego, are plagued with a devastating combination of drought, a construction-idling housing bust, and a plummeting peso, which undercuts the buying power of Mexicans who shop on the U.S. side of the border.
