Stop, Question, and Assess: Comments on Rosenfeld and Fornango

We develop three points in this commentary on Rosenfeld and Fornango's empirical assessment of the NYPD policy of stop, question, and frisk (SQF). First, we draw attention to some of the key patterns uncovered in the analysis, posing questions that we think warrant additional thought. Second, we highlight some potential ambiguities between the underlying logic model of SQF and the empirical models assumed in existing research evaluations that have important implications for the conclusions that one might draw from the available evidence. Finally, we suggest some ways in which the empirical basis for evaluating the efficacy of SQF might be strengthened.
