In 2011, D.C. Circuit Judge Brett Kavanaugh used a dissenting opinion to explain that semiautomatic handguns and rifles are “commonly-owned” and therefore constitutionally protected.
In Heller, the Supreme Court held that handguns – the vast majority of which today are semi-automatic – are constitutionally protected because they have not traditionally been banned and are in common use by law-abiding citizens. There is no meaningful or persuasive constitutional distinction between semi-automatic handguns and semiautomatic rifles. Semi-automatic rifles, like semi-automatic handguns, have not traditionally been banned and are in common use by law-abiding citizens for self-defense in the home, hunting, and other lawful uses. Moreover, semiautomatic handguns are used in connection with violent crimes far more than semi-automatic rifles are. It follows from Heller’s protection of semi-automatic handguns that semi-automatic rifles are also constitutionally protected and that D.C.’s ban on them is unconstitutional.
