Police have been the subject of increased scrutiny over the past several years, and there exists a contention that this increased scrutiny impacted officer behavior, resulting in diminished proactive policing as officers may be performing their duties less vigorously. The study examines the effect that changes in scrutiny, as measured in terms of public interest and local news coverage, had upon police officer vigor, as measured by monthly counts of pedestrian and vehicle stops. This research is unique in that it examines the effects of scrutiny emanating from local incidents separately from that related to high profile incidents that received considerable nationwide interest; the extant research is currently limited to the latter. A series of fixed-effects negative binomial regression models examine the impact of scrutiny upon vigor over time throughout all neighborhoods in the city of Philadelphia. The study finds that local and national scrutiny do not have the same impact upon officer vigor, as scrutiny emanating from national incidents generally results in increases in officer vigor, while scrutiny emanating from local incidents results in an increase in ped stops in the first month following the scrutiny, and then a subsequent decrease in both forms of vigor in the second month. This study of police officer decision-making across space and time has both theoretical and practical implications. / Criminal Justice

The Ferguson effect is a recent hypothesis that suggests police officers have been influenced by negative media coverage of police conduct. The problem this study addressed is how policing continues to deal with perception, civil liability, and accountability issues related to police misconduct when interacting with Latino and African-American communities. The research was conducted to examine influence the Ferguson effect may have had on the culture and perceptions of police officers in local police departments. With a phenomenological qualitative approach, the research data were collected from interviews with 7 police officers across 3 police departments. The theoretical background of Merton's theory of unintended consequences offered insights into how law enforcement functions and the kinds of policies that affect police-civilian relations. Data was analyzed with NVivo 12 data analysis software. Four predominant themes emerged: (1) commitment to service, (2) police officers' perception of the media, (3) impact of the Ferguson Effect, and (4) attitudes toward civil liability. The research indicates that the officers shared a strong commitment to service as well as being satisfied overall with the police department where they work. In addition, the participants acknowledged the Ferguson effect but did not believe it prevented them from performing their sworn duties. With this research study, the police officers' voices can be added to the national debate regarding the Ferguson effect and their perception of its impact on their culture in local police departments, community engagement with minority citizens, and civil liability.
