Arizona's tough new anti-immigration law, SB 1070, goes into effect on July 29. It requires local police, who have had 90 minutes of immigration law training, to check the immigration status of anyone they have probable cause to believe may be in the US illegally. Some Arizona law enforcement agencies, like the Maricopa County Sheriff's Department, are promising to vigorously enforce the new law.

Hundreds, some say thousands, of Latinos who are in the Arizona illegally, have left the state in the last three months. Many businesses that cater to this community have suffered, none more so than El Gran Mercado (The Big Market), a flea market that caters to Mexicans and others from Latin America. The once bustling Mercado is now more like a ghost town. Some say business is down more than 60% since last year.
