When is a crime a 'hate crime', and what does that term actually mean? How has living on what other people throw away become a subject for criminologists? Laurie explores some of the latest ideas on crime as he visits the British Society of Criminology Conference held this year at Leicester University. He hears from the film maker Rex Bloomstein, from Sylvia Lancaster whose daughter Sophie was murdered because of the way she looked, from Jon Garland, Senior Lecturer in Crimilogy, University of Leicester, and also from Jeff Ferrell, the Professor of Criminology from the United States who has been living out of dumpsters, skips, rubbish bins in an attempt to understand an increasingly criminalised and marginalised way of life.
