This chapter explores two key variations between cybercrime units observed in our study. To begin, this chapter considers what is likely the most important factor contributing to the proliferation and organization of computer crime units across the US—the task force modelTask force model. Computer crime task forces provide two key functions for computer crime units: they make resources available to current and potential computer crime units and provide an organizational infrastructure in which these units can embed themselves to cooperate among partner agencies. This chapter then considers two key variations between units observed in our study. The first regards the resources available to units (finances, training, and tools). Second, we noted that units were heavily structured by the relationship to digital forensic analyses dictated by the availability of in-house digital forensics capabilities, the kinds of employees (civilian, sworn, or both) assigned to such analyses, and the outsourcing of analyses to computer crime units.
