Initial charges against Seale were dismissed by Mississippi officials in 1965, but the case was reopened and he was convicted in 2007.

A U.S. magistrate judge in Detroit denied alleged members of the Hutaree Militia a hearing they sought to contest government conspiracy allegations. Nine members of the self-described group of "Christian warriors" were arrested last March and accused of plotting to murder a police officer and then use bombs and missiles to kill hundreds of other officers at the funeral in a bid to set off a national insurrection. The eight men and one woman came from Michigan, Indiana and Ohio.

Allen Goff, an 18-year-old white supremacist accused of threatening an American Indian teen at gunpoint in Billings, Mont., pleaded not guilty to felony charges of assault with a weapon. Goff leads the Montana Creators Assembly, an offshoot of the neo-Nazi Creativity Movement. In 2009, Goff was charged with the racially motivated shooting of a Latino teen in the leg, but claimed it was an accident and was only convicted last July of weapons charges. He got six months' probation.

Actor Wesley Snipes began a three-year federal prison sentence in Pennsylvania for failing to file income tax returns on millions of dollars of earnings during the 1990s and later. The 48-year-old star of the "Blade" films and "Jungle Fever" had long maintained his innocence, telling CNN's Larry King a day earlier that he wasn't a tax protester, despite abundant evidence that he actively sought out and employed bogus tax-avoidance advice from radical-right "sovereign citizen" gurus.

A federal court in Bridgeport, Conn., sentenced Edwin Westmoreland to 40 months in prison for providing weapons to an informant posing as a representative of the Imperial Klans of America. Westmoreland, a member of the Connecticut White Wolves neo-Nazi group, had pleaded guilty in June to selling guns to the informant, who he knew was a convicted felon. Prosecutors have said the plot, which allegedly involved several other White Wolves members, was part of a push to boost the group's status and geographic base in the white supremacist movement.

Following two mistrials, John Ditullio was convicted of murder and sentenced to life in prison for a 2006 knife attack that badly wounded Patricia Wells and killed her son's 17-year-old friend, Kristofer King. Ditullio, who was a recruit in a racist skinhead group called American Nazis, lived in a trailer park with fellow members in New Port Richey, Fla., next to Wells' home. Ditullio and his fellow neo-Nazis reportedly despised Wells because she sometimes had black house guests.
