The Justice Department is reportedly preparing a major expansion of its definition of racial profiling in order to curb the targeting of different groups. Under the new rules, federal agents will be barred from considering religion, national origin, gender and sexual orientation during the course of investigations. Profiling was banned under the Bush administration in 2003, but with exceptions for national security cases and also with a more limited definition. Critics say the exceptions have allowed for significant profiling of two key groups — Muslims in counterterrorism cases and Latinos in immigration ones. It is unclear, however, if the new rules will undo the national security exemption.
