Five days after it overturned Hawaii’s law, the Court agreed to hear a pair of cases involving bans on widely owned rifles that politicians tendentiously describe as “assault weapons.” A dozen states, beginning with California in 1989, have enacted such laws, which hinge on arbitrarily prohibited features such as folding stocks, pistol grips, and barrel shrouds.
The rifles targeted by these laws are rarely used by criminals but commonly used by law-abiding Americans, who own more than 30 million of them. The latter point is constitutionally relevant because the Supreme Court has said the Second Amendment applies to “bearable arms” that are “in common use” for “lawful purposes like self-defense.”
The long-simmering question posed by these cases is whether the Second Amendment guarantees “the right to possess AR-15 platform and similar semiautomatic rifles.” If so, other restrictions on the arms Americans are allowed to buy, such as magazine limits and California’s handgun specifications, may be vulnerable to constitutional challenges.
The decided cases also have potentially broad implications. If drug use, by itself, does not justify disarming someone, what about a nonviolent felony conviction? And if Hawaii’s broad restriction on public gun possession was unconstitutional, the far-reaching, location-specific bans imposed by states such as California and New York likewise seem legally dubious.
Nearly two decades after recognizing a constitutional right to arms, the Supreme Court is beginning to address lingering questions about its contours. Control-happy politicians probably will not like the answers.
