The FBI's power to collect, use and map racial and ethnic data in order to assist the FBI's "domain awareness" and "intelligence analysis" activities is described in the 2008 FBI Domestic Intelligence and Operations Guide (DIOG). The FBI released the DIOG in heavily redacted form in September 2009, but a less-censored version was not made public until January 2010. Although the DIOG has been in effect for more than two years, very little information is available to the public about how the FBI has implemented this authority.
