"We do know there are 140,000 workers, they're part of something called LUCA -Local Update of Census Addresses. And what they're doing is developing a master address file for all households in America.

They are now going to door-to-door to every residence in the country." --Wednesday's 4th hour guest, privacy advocate Katherine Albrecht reporting on the 2010 census plan.
