Diane Vaughan reconstructs the Ohio Revco case, an example of Medicaid provider fraud in which a large drugstore chain initiated a computer-generated double billing scheme that cost the state and federal government half a million dollars in Medicaid funds, funds that the company believed were rightfully theirs. Her analysis of this incident—why the crime was committed, how it was detected, and how the case was built—provides a fascinating inside look at computer crime. Vaughan concludes that organizational misconduct could be decreased by less regulation and more sensitive bureaucratic response.
