OAKLAND, Aug. 10 – A federal judge’s order to liquidate the assets of Your Black Muslim Bakery will shutter one of this city’s black nationalist institutions, a step called long overdue by many members of the clergy and community activists. They had veered far, far away from the basic tenets of the Muslim faith, said Amos C. Brown, senior pastor at the Third Baptist Church in San Francisco. They had become agents and perpetrators of terror and vigilantism. The bankruptcy ruling late Thursday to pay off some $900,000 in debt and back taxes came a week after the killing of a local journalist, Chauncey W. Bailey Jr., a case in which a handyman employed by the bakery is a prime suspect. Mr. Bailey, who had been investigating the bakery’s finances for a newspaper story, was shot at close range in daylight in downtown Oakland on Aug. 2.
