Bill Cosby ruffled feathers, raised eyebrows and said a mouthful when, at a Howard University black-tie celebration of the 50th anniversary of Brown v. Board of Education, he launched into a rift about "the lower economic people" not holding up their end of the bargain in the wake of Brown. "We can't blame White people," Cosby said, for an array of problems. "The issue," he said, "is personal responsibility." Pundits have had a field day both attacking and defending Cosby. Most African Americans are frustrated by petty crime in the community, by the police brutality that comes with that petty crime, by parents who cannot seem to control their children. Some may have unleashed Cosby-like riff's, but in private and at more appropriate times. Some are frustrated because 50 years after the Supreme Court said that the nation's schools should desegregate "with all deliberate speed," the schools are resegregating, racial economic differences remain persistent, and some don't sense answers to the question--how long will this go on?
