PSP Traffic Stop Data Analysis Reflects Impartial, Evidence-Based Policing | State Police | Commonwealth of Pennsylvania

Harrisburg, PA – As part of the Shapiro Administration’s commitment to transparency and fair policing, the Pennsylvania State Police (PSP) today announced the release of an independent analysis of data collected from all trooper-initiated traffic stops conducted in 2025. The report was conducted by a research team based at the University of Cincinnati and led by Dr. Robin Engel, Senior Research Scientist at The Ohio State University’s John Glenn College of Public Affairs and one of the nation’s leading policing researchers. The report represents the latest findings from PSP’s traffic stop data collection initiative, which is designed to strengthen public trust, enhance trooper and motorist safety, and inform policy and training.

Why ShotSpotter Case Clearance Depends on More Than Tech – PoliceResearchHub

Key Takeaways
Cameras and gunshot sensors, alone or together, did not improve case clearance for fatal or nonfatal shootings in Chicago. A 15-year, matched quasi-experimental study of 6,068 fatal and 64,884 nonfatal shootings (2005 to 2019) found null results across every treatment condition tested.
Shootings exposed to gunshot detection technology (GDT) were actually cleared at lower rates than matched control incidents (25.9% vs. 39.2% for fatal shootings; 25.1% vs. 30.6% for nonfatal shootings), though once the researchers controlled for other factors, the difference wasn’t statistically significant.
Camera coverage (CCTV) showed essentially no relationship to clearance for gun violence, consistent with prior research showing CCTV’s investigative benefits concentrate in theft and disorder cases, not shootings.
The one bright spot: Chicago’s Strategic Decision Support Centers (SDSCs), district-level hubs that combine technology with dedicated staff and crime analysts, were linked to 19% to 24% higher odds of clearance in nonfatal shooting cases.

Professionalism and performance – police leadership for the future | College of Policing

Executive summary
The police leadership commission has undertaken the most comprehensive examination of police leadership in England and Wales in a generation. The independent commission was set up by the College of Policing with the support of the Home Office in October 2025.

Bringing together expertise from across policing, the private sector, academia, the military and politics, we have heard from thousands of officers, staff and members of the public through our force visits, call for evidence, survey work, roundtables and focus groups. Our work has covered the entirety of the policing workforce, including officers, staff and volunteers working at all levels.

We have seen outstanding examples of leadership and delivery across policing, often in the most challenging circumstances.
