Robin Lustig begins his journey in Washington DC where the first amendment is housed in the National Archive and serves as an almost sacred document. In this programme he asks how Courts around the world make decisions on Free speech. Can they find a line in the sand that shouldn’t be crossed? How do they decide what is, in the modern parlance, ‘hate speech’ and what is merely strongly expressed personal opinion? And can they ever be more than extensions of the political environment they inhabit?
