Yesterday an illegal immigration smuggling ring was busted in Arizona (link):

About 800 federal agents, local police and deputies swarmed the streets today targeting shuttle van operators that specialize in moving people from Mexico... They are accused of using the vans to transport illegal border crossers in an elaborate human smuggling system.

Over to Derechos Humanos, a group linked to the Mexican government that's headed by Pima County (U.S.) public defender Isabel Garcia:

Margo Cowan of Derechos Humanos says, "Today our community was attacked. We were viciously attacked by agents with automatic weapons, with masks covering their faces put up roadblocks on out streets and stopped our brothers and sisters mothers and fathers men and women and children and ask for the documents that's outrageous."

Derechos is a small, local group akin to Casa de Maryland and they're more openly extremist than, say, the National Council of La Raza. However, they're still a mainstream group within their circle: they're headed by a public employee, and she's also close with U.S. Rep. Raul Grijalva.
