A Bill Moyers documentary on the aftermath of apartheid in South Africa won the highest honor today at the Alfred I. duPont-Columbia University Awards for broadcast journalism.

"Facing the Truth With Bill Moyers," produced for Public Affairs Television, earned a Gold Baton for its unflinching examination of South Africa's violent history.

"Much of the violence on television is gratuitous," said Columbia University President George Rupp. "But sometimes it is key to the story, so that we can prepare ourselves for the years ahead."

The awards presentation will be televised Thursday on PBS.
