Thin Blue Line Act

Sponsored by Mike BraunSen. Mike Braun (R-IN)
Introduced February 15, 2023

AI-Generated Summary

Updated January 20, 2026 at 3:39 AM UTC

The Thin Blue Line Act amends the federal criminal code to create a new aggravating factor for the death penalty. It targets anyone convicted of murder who kills or attempts to kill a law‑enforcement officer, firefighter, or other first responder while they are performing official duties, because of those duties, or because of their public‑employee status. This change makes such murders eligible for harsher sentencing, including the death penalty, and applies to federal cases involving these public‑safety officers.

Key Provisions

  • Adds a new aggravating factor (paragraph 17) to 18 U.S.C. §3592(c) for the death penalty.
  • Specifies that killing or targeting law‑enforcement officers, firefighters, or other first responders qualifies as an aggravating circumstance.
  • Defines the covered circumstances as the victim being engaged in official duties, being targeted because of those duties, or being targeted due to their status as a public official or employee.
