Prohibition sent American progress reeling backward and led to new social ills, including bootlegging and organized crime, documentary film maker Ken Burns told a National Press Club on Monday.
The last segment of Burns' exhaustive three-part series "Prohibition" airs Tuesday night on PBS.
What he learned from doing "Prohibition," he said, is how little he really knew about it, the social forces that shaped it.
"Drunkenness was a huge social problem," he said. "We were known as a nation of drunkards."
