Professor Mary Fulbrook's book Reckonings won the 2019 Wolfson History Prize for its unique approach to the Holocaust, and in particular, those who perpetrated the atrocities. Fulbrook claims that the West German justice process was far too lenient on many ex-Nazis, who had condemned thousands or even hundreds of thousands to their death. She talks to Dan about the justice process, and what drove people to commit war crimes, and what stopped people from resisting them. Producer: Peter Curry
