To direct the Attorney General to conduct a study on the efficacy of extreme risk protection orders on reducing gun violence, and for other purposes.

HR 545 requires the Attorney General to study how effectively extreme risk protection orders (ERPOs) reduce gun violence. The study must be completed within one year of the bill's enactment and conducted by the Bureau of Justice Assistance. This bill does not change existing laws or impose new requirements on individuals; it only directs a federal study on ERPOs, which are court-ordered temporary firearm removals for high-risk individuals. The summary focuses solely on the bill's procedural mandate, not on policy outcomes.
