Drawing both on the proponents of realist criminology and on those who have leveled critiques of the approach, Steinmetz illustrates the contours of a realist criminology of computer crime by considering definitions of harm with online crime, the idiosyncrasies of online locality and community, the social relations of computer crime, the tension between piecemeal reform and structural changes, and other matters. Furthermore, Steinmetz surveys the methodological dimensions of computer crime research, offers a critique of positivist “computational criminology,” and posits an agenda for computer crime policy. is an essential reading for all those engaged with cybercrime, realist criminology, criminological theory, and social harm online.
