I'm not sure I love case's facts but the South Dakota Attorney General filed a brief in support of a U.S. Supreme Court firearms case.
Something tells me Tom Miller didn't file anything similar....
The brief was filed in Abramski v. United States of America. That case challenges whether federal law prohibits citizens from legally buying a firearm from a licensed dealer with the intention of then selling that gun to another private citizen who also is legally allowed to purchase and own firearms. The Department of Justice argues that the citizen who buys and then sells the gun is acting as a “straw purchaser,” which they claim is illegal under several federal statutes.
The States, however, argue that Congress has never passed a federal law that prohibits such purchases. At most, the laws relied on by the United States prohibit private citizens from selling guns to people who are prohibited from owning firearms, such as minors, convicted felons, or people who have been diagnosed as having mental illnesses.
The States’ amicus brief is in support of a former Roanoke, Va., police officer, Bruce Abramski, who purchased a gun in 2009 and sold it to his elderly uncle, who lived in Pennsylvania. Both Abramski and his uncle could legally own firearms and made the transaction in accordance with Pennsylvania gun laws. However, federal authorities prosecuted Abramski on the grounds that he made false statements on the gun purchase form.
