Filmmaker Ken Burns's latest documentary, "Prohibition" will air in October and it tells the history of the rise and fall of the 18th Amendment to the U.S. Constitution. The saga of prohibition goes far beyond the oft-told tales of gangsters, rum runners, flappers and speakeasies. It is the story of unintended consequences and a nation divided by politics, religion and , individual rights and responsibilities. On today's program, we begin a six-part series on the legacy of prohibition: how it transformed America and the challenges we face as we continue to wrestle with alcohol and drug abuse.
