Book excerpt: The Second Edition of this best-selling text provides a fully revised and up-to-date critical analysis of a wide range of issues surrounding young people, disorder and crime. How and why have certain aspects of young people's behaviour come to be perceived as 'anti-social' and 'criminal'? Are young people now more of a threat than ever before? How can we make sense of New Labour's youth justice reforms? Is the youth justice system soft on crime? Are young people more in need of protection than disciplinary punishment? To develop a comprehensive criminology of youth the book deliberately moves.
