According to some politicians, policing experts, and other pundits, the success of zero tolerance policing programs has been established through reductions in the number of recorded o enses. However, there may be adverse side e ects that accompany these crime-‹ghting programs including the possibility of increased o­cer misconduct (e.g., illegal searches). A theoretical framework is outlined and evidence is gathered (utilizing both o­cial data and self reports) to analyze the extent to which aggressive crime control policies inœuence o­cers. Results indicate that zero tolerance initiatives can lead to increased o­cer misconduct. Speci‹c strategies for policymakers to cope with these results are discussed.
