Ethan's Law This bill establishes a framework to regulate the storage of firearms on residential premises at the federal, state, and tribal levels. At the federal level, the bill establishes statutory requirements for firearms on residential premises to be safely stored if a minor is likely to gain access without permission or if a resident is ineligible to possess a firearm. An individual who violates the requirements is subject to criminal penalties. A firearm stored in violation of the requirements is subject to seizure and forfeiture. At the state and tribal levels, the bill requires the Department of Justice to award grants to implement functionally identical requirements for the safe storage of firearms.
