This article reviews research and policy on officer-involved domestic violence (OIDV) and seeks to provide motivation for uniformity of policy implementation and office response to OIDV, calling for transparency via research and reporting. The authors note that very little is known about the full extent of OIDV and that, although the International Association for Chiefs of Police has developed model policies, the extent to which agencies adopted these policies across the United States remains unclear. They also note that whereas officer training on OIDV is rare, pilot studies examining the use of new curriculum show promise.
