It might not get the news coverage it deserves with everything else going on at the moment, but the unanimous ruling by a three-judge panel of the 6th U.S. Circuit Court of Appeals in Cincinnati against a federal gun law is a very big deal. The court held that the federal ban on gun ownership by people who have been committed to a mental institution is an unconstitutional violation of the Second Amendment. Rulings of that caliber (if you’ll pardon the pun) don’t come down all that often. The previous instance was the Supreme Court’s Heller ruling against Washington D.C.’s firearms ban in 2008, which those on both sides of the gun control debate would agree was a very big deal.
