Author Dan Gretton discusses his book I You We Them, which examines the psychology of individuals who organised and implemented some of the worst crimes against humanity, from the Holocaust to human rights violations in Nigeria. In conversation with Rachel Dinning, he introduces the concept of the ‘desk killer’ – a perpetrator who is responsible for murder without taking an active role in the killing.
