This report is intended for use by law enforcement officials, prosecutors, judges, practitioners, and others concerned with the problem of domestic violence. The report, from the National Center on Full Faith and Credit, highlights the most promising practices in use around the country and in tribal jurisdictions for enforcing domestic violence firearm prohibitions. The information in this report is presented in three main sections. Section I presents an overview of domestic violence firearm laws at the Federal, State, and tribal levels, and examines the relationship between Federal and State/tribal firearm laws. Section II presents examples of model programs and promising practices to remove firearms from domestic abusers. The examples are summarized according to the different areas of the criminal justice system: law enforcement, the courts, prosecutors, probation, firearm prohibition databases, and legislative reform. Section III discusses eight principles that all the successful programs have in common. Appendix
