TACKLING NEAR REPEAT CRIME

This document is designed to assist law enforcement professionals in identifying and responding to near repeat patterns of victimization. Several open source tools are broadly discussed as they are necessary to quantify near repeat patterns and develop interventions; we encourage you to review those program’s user manuals for more details.

This report will help you:

  1. Understand what near repeat patterns are and why they are useful to policing
  2. Evaluate global and local patterns of near repeat
  3. Formulate appropriate responses these patterns
  4. Develop program metrics to understand the effect of the intervention
  5. Evaluate a near repeat crime prevention program

Agents of Chaos and Cruelty: How the Trump Administration’s National Deportation Policing Force Has Attacked American Communities | American Civil Liberties Union

This ACLU research report, Agents of Chaos and Cruelty, documents widespread civil rights violations carried out by immigration agents during the first year of President Trump’s second term. The report examines immigration enforcement incidents in eight states – representing a cross-section of the country and reflecting varying degrees of federal law enforcement presence and personnel surges – and found that over 400 of the more than 1,200 immigration enforcement incidents examined involved misconduct by immigration agents. The report ends with detailed recommendations urging policymakers to call for transformative change to our immigration system, in recognition that it is broken and dangerous to human rights.

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.
