Lovely meeting the artist Bob and Roberta Smith. He was interviewing me on the differences between protests across the generations from the hippies to the Occupy movement for his documentary on the history of protest for BBC Four.

History of Protest, Bob and Roberta Smith, BBC Four

‘Bob and Roberta Smith, an artist known for eye-catching placards with slogans like ‘Make Art Not War’, has for years waged his own eccentric political campaigns. In recent years, he’d begun to lose faith in protest but suddenly it’s all the rage. From the Brexit vote to Black Lives Matter it seems the world is reclaiming its right to protest. In this film, Bob sets out to discover what’s getting everyone so angry in a wry, opinionated and passionate investigation into our age of activism.’ See the full programme on iplayer here
