Mass public shootings in the U.S. spark debate about their impact on gun control support.

This article explores how such events influence public opinion and policy demand, integrating concepts like focusing effects, contextual impacts, and threat perception to argue that proximity to a shooting makes gun violence salient and increases support for stricter controls.

Data & Methods:

* Multiple sources of mass shooting data combined with large-N survey datasets.

* Panel data analysis used to replicate core findings over time.

✅ Key Findings:

* Living near a mass shooting significantly raises public support for gun control, independent of political partisanship.

* The effect's strength depends on specific salience factors: repetition, magnitude (seriousness), and recency.

Why It Matters?

* These findings reveal a context-driven process where traumatic events can override partisan divides to fuel policy feedback.

* This suggests mass shootings could serve as powerful catalysts for gun control advocacy across the political spectrum.
