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.

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.
