Can a state witness be cross-examined as to whether he had a generalized prejudice against black persons?

"[W]e find no basis for the trial court's limitation of cross-examination as to whether the state witness possessed a generalized prejudice against black persons. While the court's determination to limit cross-examination should not be disturbed absent an abuse of discretion, [citation omitted] we conclude that the present case involves such an abuse of discretion. In balancing considerations of unfair prejudice with the probative value of questions regarding a witness's racial bias, such questions have elsewhere been found proper and not unfairly prejudicial.
