Book excerpt: In Trusted Criminals, David O. Friedrichs, author of numerous articles in leading criminal justice, criminology, and sociology journals, offers a comprehensive study of the world of white collar crime. Beginning with a thorough explanation of the historical development of the concept of white collar crime, Friedrichs then draws readers deeply into this arena of crime by exploring many aspects of the subject, including alternative theories for explaining white collar crime; the role of media (and other agents) in effecting an image of white collar crime; those parties - from whistleblowers to investigative reporters - who expose such crime; the challenges involved in studying white collar crime; various forms of white collar crime - including corporate and occupational crime, governmental crime, state-corporate crime, finance crime, technocrime, and more; investigating, policing, prosecuting, defending, and adjudicating white collar crime and social policy options for responding to white collar crime.
