WASHINGTON, July 29 - The Census Bureau has provided specially tabulated population statistics on Arab-Americans to the Department of Homeland Security, including detailed information on how many people of Arab backgrounds live in certain ZIP codes.
The assistance is legal, but civil liberties groups and Arab-American advocacy organizations say it is a dangerous breach of public trust and liken it to the Census Bureau's compilation of similar information about Japanese-Americans during World War II.
