Supermax - Western Rule

Laurie Taylor explores the growth of high security prisons in America alongside the increased use of solitary confinement with criminologist Dr Sharon Shalev whose book 'Supermax' examines both topics. Laurie's second discussion is with Professor Ian Morris whose major new book 'Why The West Rules- For Now' examines the rise and fall and rise of Eastern and Western societies and asks whether it's possible for historians to predict the future with any confidence.
