Towns Rethink Laws Against Illegal Immigrants :New York Times

"Within months, hundreds, if not thousands, of recent immigrants from Brazil and other Latin American countries had fled. The noise, crowding and traffic that had accompanied their arrival over the past decade abated. The law had worked. Perhaps, some said, too well. With the departure of so many people, the local economy suffered. Hair salons, restaurants and corner shops that catered to the immigrants saw business plummet; several closed. Once-boarded-up storefronts downtown were boarded up again."
