Alabama’s ruling class has dug in against the storm it caused with the nation’s most oppressive immigration law. Some of the law’s provisions have been blocked in federal court; others won’t take effect until next year. But many Alabamans aren’t waiting for things to get worse or for the uncertain possibility of judicial relief or legislative retreat. They are moving to protect themselves, and summoning the tactics of a civil rights struggle now half a century old.

The law was written to deny immigrants without papers the ability to work or travel, to own or rent a home, to enter contracts of any kind. Fear is causing an exodus as Latinos abandon homes and jobs and crops in the fields. Utilities are preparing to shut off water, power and heat to customers who cannot show the right papers.

Alabama is far from alone in passing a law whose express aim is misery and panic. States are expanding their power to hasten racial exclusion and family disintegration, to make a particular ethnic group of poor people disappear. The new laws come cloaked in talk of law and order; the bigotry beneath them is never acknowledged.
