Borders: Laurie Taylor explores the control of national borders. He talks to Nira Yuval Davis, Director of the research centre on Migration, Refugees and Belonging at the University of East London and co-author of a new book which asks why borders have moved from the margins into the centre of political life and turned many ordinary citizens into untrained border guards. They’re joined by Jeremy Slack, Assistant Professor of Geography at the University of Texas, who charts the way in which Mexican deportees from the United States become the targets of extreme drug related violence upon their return to Mexico.
