This is the second of two podcast episodes this week dealing with the aftermath of the attempted assassination of Donald J. Trump and the causes and effects of political violence in America.

Political violence comes in different forms. A political movement might have a paramilitary force that engages in extrajudicial mayhem. A lone assassin may or may not be motivated by political ideas. Mobs break out in sheer anger and frustration at injustice, real or perceived. In this episode, Oxford Brookes historian Roger Griffin, an expert on socio-political movements, fascism, and terrorism, delves into the causes of political violence that are often difficult to clearly discern or contain.
