The latest academic research has thrown up a a new link between those much debated phenomena; screen violence and rising crime rates.
According to researchers at the London School of Economics the problem is not too much celluloid blood and gore but a dearth in contemporary films, of heroic characters who always play by the rules. Children, say the researchers, are twice as likely to imitate positive, anti-violent images as they are to copy violent ones.

Michael Winner and David Puttnam debate the subject on pages 15 and 16.
