MEMO speaks to Dr Rob Faure Walker to discuss the crackdown on free speech on Palestine in UK schools and understanding why the country's anti-extremism programme is flawed and racist. Faure Walker is a lecturer at UCL and author of 'The Emergence of ‘Extremism’ Exposing the Violent Discourse and Language of ‘Radicalization’'. He also runs PREVENT digest, an independent not-for-profit organisation that has been gathering evidence on the impact of the UK's counter radicalisation programme.
