TV talk show host Arsenio Hall, director John Singleton and rap artists Eazy-E and Public Enemy were discussed as potential targets by a white supremacist group that intended to start a race war by bombing a black church and killing Rodney King. The ring was broken up Thursday by the FBI, capping an 18-month undercover investigation.Eight people, members of several different supremacist groups — including Fourth Reich Skin Heads and the White Arayan Resistance — were arrested during afternoon raids in four local communities. Authorities also seized a large cache of guns and pipe bombs as well as Nazi uniforms. In addition to targeting the First African Methodist Episcopal Church (AME) in Los Angeles, home to several high-profile black community leaders, sources close to the investigation said Hall and Singleton were among those considered good targets by one of the groups. The socially active First AME church has been especially prominent since the 1992 Los Angeles riot. FBI spokesman John Hoos said that the rappers were named in the affidavit used to secure arrest warrants, but was unable to confirm that Hall and Singleton were targeted. A source said some of the celebrities were informed of the probe so they could take protective steps. The entertainers could not be reached for comment.
