Mexican and Latino janitors hold a candl

Mexican and Latino janitors hold a candlelight vigil calling for federal immigration reform, in response to the tough new Arizona law giving the police new stop and search powers, outside their place of work in Los Angeles on May 20, 2010. Mexican President Felipe Calderon urged the US government to repair an outmoded immigration system and do more to ensure that illegal guns do not flow across the countries' shared border. The Mexican leader renewed his call for an overhaul of US immigration laws that would offer up to 12 million illegal immigrants in the United States, many of them Mexicans, a path to US citizenship as well as strongly criticizing a new Arizona law that has enraged Hispanics and stoked fears of racial profiling.
