Arizona’s controversial immigration law may damage a lot more than the state’s image, as Rep. Raúl M. Grijalva argued in his OtherWords op-ed. It could also break up families. As Michelle Chen reports on the Colorlines blog, a new study by child advocacy group First Focus finds that more than five million American children have at least one parent who is an undocumented immigrant. “Arizona’s new racial profiling legislation could open up countless opportunities for local law enforcement to break up families by putting undocumented parents on the fast-track to deportation,” Chen writes.
