PurposeThe purpose of this article is to describe an innovative research methods framework designed to address some of the persistent challenges to a social scientific understanding of civilian-led police oversight commissions.Design/methodology/approachThe project design begins by acknowledging that oversight commissions take multiple and varied forms, which are contingent on local histories, institutional dynamics and discursive strategies for indexing racial inequality. The authors find such variation not to be an impediment to insightful research design. Rather, the methodological frame makes use of multi-sited ethnographic methods, organized at the county level across three research clusters (in this example, Milwaukee Co, WI; San Diego Co., CA; and Washtenaw Co, MI), to draw attention to the effects of such multiplicity to complicate, localize and render visible the specific practices of policing and its critique through civilian oversight.FindingsAmongst an increasing national concern with the racialized nature of police violence, one evolving strategy for police reform among municipalities is to establish civilian oversight boards that can monitor, make recommendations for, and potentially direct police policy. However, there is very little research on such commissions, leaving many unanswered questions for proponents of evidence-based criminal justice policy. One reason for this lack is that the tremendous variability of such commissions has led some researchers to abandon hope for a comparative analysis which might offer generalizable conclusions beyond individual case studies. Lessons learned from previous reform efforts suggest that without a solid evidentiary basis, such reform efforts can easily succumb to institutional inertia or even failure. This danger is especially present when policy and practice recommendations are not based on research designs particularly attuned to making audible the experiences and concerns of the most marginalized targets of police attention.Originality/valueThe value of this method rests in its ability to provide comparative insights into the ways in which oversight commissions operate within a broader pluralized security landscape that both makes possible and constrains democratic participation along racial lines. The method contextualizes and renders audible ways of understanding, evaluating, and practicing democratic community as it is articulated through the issue of police and its oversight.
