'Against Security', a new book by the acclaimed American sociologist, Harvey Molotch, explores the complex systems which are designed to make us feel safe in public places. He tells Laurie Taylor why he thinks that security measures in airports and subways, post 9.11, have damaged the pleasure and dignity of our daily lives. They're joined by the design critic, Stephen Bayley. Also, Sociology's failure to address the financial crisis. The social scientist, Alberto Toscano's paper 'Reformism and Melancholia' argues that the twin spectres of Fordism and Keynesianism have prevented sociologists from imagining a future beyond austerity.Producer: Jayne Egerton.
