PurposeWhile the past few decades have witnessed a substantial number of studies on public attitudes toward the police, a relatively thin line of inquiry has focused exclusively on low income urban Black-Americans, and especially street-identified Black populations. The purpose of this paper, however, is to examine trust in police amongst street-identified Black men and women.Design/methodology/approachRelying on a street participatory action research methodological approach, the authors collected survey data (N = 520) from two low-income unban Black neighborhoods, to examine the effects of an instrumental model versus an expressive model on procedural- and outcome-based trust in police.FindingsThe findings suggested a community sample of street-identified Black men and women were able to differentiate between procedural- and outcome-based trust. The instrumental model was better in predicting procedural-based trust in police, while the expressive model accounted better for outcome-based trust in police.Research limitations/implicationsImplications for street participatory action research methodology, future research and policy are also discussed.Originality/valueThis paper is an original manuscript.
