Saturday, 8.30pm, SBS One This is the fifth episode in this epic documentary series from Ken Burns about the rise, rule, and inevitable fall of the 18th amendment of the US constitution, banning the manufacture, sale, and transportation of alcohol. During the 13 years of Prohibition, millions of Americans reacted by turning their backs on the moralistic universe it represented. The enshrining of a faith-driven moral code in the constitution paradoxically caused millions of Americans to rethink their definition of morality. Burns, of course, is the Emmy award-winning filmmaker whose documentaries include, most memorably, The Civil War series. Tonight’s final episode, A Nation of Hypocrites, brings to a close a great story, sexy and violent, dangerous and viscerally dramatic. By the close of the 1920s, many Americans blamed the moralistic laws for the rise of criminal syndicates, gangsters and promiscuity, and there was a sense that the entire government was corrupted. When the Depression hit they began to re-examine their priorities and by December 1933, Prohibition’s reign came to an end under president Franklin D. Roosevelt.
