Undocumented immigrants are searched before boarding a deportation flight in Mesa, Ariz., last June. Since the passage of the state's immigration law two years ago, thousands of illegal workers have left.
The U.S. Supreme Court will hear arguments next week on the most divisive immigration law in recent memory. Arizona's Legislature passed SB 1070 two years ago, but much of it has been put on hold pending the court's decision.
Still, supporters say the law has achieved one of its stated goals: Thousands of illegal immigrants have self-deported, leaving the state on their own. The real reason — and consequence — of such a demographic shift may be more complex, however.
