As of December 28, 2025, the "Violence Squeeze" in the United States has produced a complex statistical signal. While criminologists at Northeastern University report that mass killings (4+ dead) hit a 20-year low this year, the "Engagement Signal" of mass shootings (4+ shot) remains a persistent structural artery of American life. According to the Gun Violence Archive, 2025 saw over 400 mass shooting incidents, claiming hundreds of lives and leaving thousands with life-altering kinetic trauma.
This report evaluates the "High-Casualty Events"—incidents that disrupted the 2025 social grid and forced a national re-audit of security protocols and legislative moats.

Verdict: The "Normalization" Squeeze
As we enter 2026, the US is trapped in a Statistical Volatility. While mass killings are down, the frequency of shootings remains high enough to drive a "Public Perception Squeeze," where 33% of Americans now avoid certain public spaces out of fear. The companies and institutions that win in 2026 will be those that provide High-Fidelity Security Moats for their citizens.
