The Justice Department will begin keeping numbers on hate crimes committed against Sikhs and six other groups, in connection with Monday's one-year anniversary of the killing of six Sikh worshippers in Oak Creek, Wis. Attorney General Eric Holder made the announcement Friday in a blog post, which The Associated Press obtained ahead of its official release. Holder said FBI Director Robert Mueller had approved a recommendation from the agency's advisory policy board to track hate crimes against Sikhs, Hindus, Arabs, Buddhists, Mormons, Jehovah's Witnesses and Orthodox Christians.
