Opponents of Arizona's hardline immigration enforcement law contend that emails sent, received and forwarded by a former legislator who championed the law support allegations it was racially motivated. Dozens of emails are cited in a new legal effort by the American Civil Liberties Union and other civil rights groups to block police from enforcing the Arizona law's so-called "show me your papers." The groups said the emails and other material reveal that ex-Sen. Russell Pearce and other supporters of the law embraced discriminatory views and bent the truth about immigration-related matters.
