The Supreme Court announced Tuesday it will decide whether states can ban AR-15s and similar semiautomatic rifles, setting up a confrontation that could strip away protections enacted after some of the nation's deadliest mass shootings. The justices will hear appeals challenging bans in Connecticut and the Chicago area, with arguments expected this fall.
The decision puts laws in about a dozen states at risk, affecting major population centers including New York, Los Angeles and Washington, D.C. These measures represent the primary legislative response available to states after Congress allowed a national assault weapons ban to expire in 2004. Democrats have pushed to renew federal restrictions following repeated mass casualty events, while states like Virginia and Rhode Island have recently passed their own protections.
A Response to Sandy Hook
Connecticut's law came directly after a mass shooter used an AR-15 to kill 20 children and six educators at Sandy Hook Elementary in 2012, now marking the 14th anniversary of that tragedy. The state argues these weapons can be banned because they're similar to military-grade firearms and have become the preferred choice of mass shooters. Janet Carter, managing director of Second Amendment litigation at the gun-control group Everytown Law, said, "These laws are critical public safety measures, and they are consistent with the Second Amendment."
Attorneys for Cook County, Illinois, whose ban dates back 33 years to 1993, emphasized the human toll in their filings. "The trauma that assault weapon massacres have inflicted on the public at large has been staggering," they wrote. Lower courts have upheld both laws, recognizing states' authority to regulate weapons designed for rapid, high-casualty violence.
Gun Rights Groups Push Back
Gun rights organizations frame the bans as unconstitutional restrictions on widely owned firearms. Adam Kraut, executive director of the Second Amendment Foundation, said, "The Second Amendment protects arms in common use for lawful purposes, and it's hard to argue that a type of rifle that potentially outnumbers Ford F-150 trucks in America doesn't meet that standard."
Challengers wrote that "if the Second Amendment does not protect the most popular rifles in the country, it is hard to see how it protects any firearms at all," aside from handguns kept in the home. Four conservative justices on the nine-member court had signaled it was only a matter of time before they took up the issue.
A Court Expanding Gun Access
The case arrives at a Supreme Court that's systematically expanded gun rights. In 2022, marking the 4th anniversary this year, the court handed down a landmark ruling that broadened Second Amendment protections and triggered challenges to firearm laws nationwide. This term alone, justices struck down gun carry restrictions in Hawaii and a federal ban on gun ownership by marijuana users, backing Second Amendment claims in both cases.
The court has upheld some restrictions, including a law barring people under domestic-violence restraining orders from having guns. But the trajectory is clear. Also Tuesday, the court declined to hear cases over restrictions on guns for young adults under age 21, an issue that's sharply divided lower courts in recent years.
Why This Matters:
This case will determine whether communities can protect themselves from weapons designed for mass casualties, even as mass shootings remain a persistent threat to American life. The laws at stake represent the most significant tools states have to respond to gun violence after the federal government stepped back. Connecticut's ban emerged from one of the worst school shootings in U.S. history, a direct legislative response to preventable deaths. If the court strikes down these protections, it will eliminate one of the few remaining avenues for democratic regulation of firearms, leaving states powerless to address weapons that appear repeatedly in mass casualty events. The ruling will affect millions of people living in states that have chosen, through their elected representatives, to limit access to military-style weapons. It's a test of whether public safety measures can survive a court that's shown consistent willingness to expand gun access, even when communities bear the costs.
