Mexico wants migrant rights in U.S., but is harsh to undocumented Central Americans: The hundreds of thousands of undocumented Central American migrants in Mexico suffer mostly in silence. Considered felons by the Mexican government, they fear detention, rape and robbery. Police and soldiers hunt them down at railroads, bus stations and fleabag hotels. Sometimes they are deported; more often officers simply take all their money. While Mexico demands the humane treatment of its citizens who migrate to the U.S., it appears to be unable to guarantee similar rights for Central American migrants to this country.
