Last week, a federal judge in Texas held that the longstanding law prohibiting persons subject to domestic violence restraining orders from possessing firearms violates the Second Amendment. The court's decision in United States v. Perez-Gallan upends the legal regime created to protect survivors and poses a lethal threat to not just victims of domestic violence, but the public at large. The opinion relies on flawed historical analysis to strike down key domestic violence protections that we know save lives every day.
