'Editors Welsh, Braga and Bruinsma bring readers an excellent collection of writings that justify, and strongly advocate for, the use of scientific method in criminology … This comprehensive and very well-organized work would be an excellent volume for academic use in research methods courses in criminology; it would also clearly illustrate the complexities of crime policy for the policy maker. Summing up: highly recommended.' F. E. Knowles, Choice
