Sandy Hook families are urging the U.S. Supreme Court to uphold state and local bans on AR-15-style semiautomatic rifles, arguing the weapons’ lethality justifies restrictions intended to prevent mass casualties.
The parents of five of the 20 first-graders killed in the 2012 Newtown, Connecticut, massacre, along with relatives of one of the six educators who died, filed a friend-of-the-court brief on Wednesday in two cases challenging bans in Connecticut and the Chicago area. The justices are slated to hear oral arguments in both matters on December 2.
In their filing, the relatives described the 2012 attack by an untrained, 112-pound 20-year-old armed with an AR-15-style rifle as evidence of the firearm’s “unusual and extreme lethality,” saying they want to prevent other families from suffering through another AR-15 killing spree.
Gun rights proponents and plaintiffs behind the cases contend that prohibitions on semiautomatic rifles violate the Second Amendment, noting that such firearms are lawfully possessed by millions of Americans. Supporters of the bans counter that the rifles were developed for military purposes, pose outsized risks to civilians, and should be regulated similarly to machine guns.
More than 40 additional individuals and organizations, most supporting the restrictions, also submitted amicus curiae briefs on Wednesday. These filings come from parties not directly involved in the litigation.
The Sandy Hook gunman, Adam Lanza, forced his way into the locked elementary school and fired more than 150 rounds in about four minutes with a Bushmaster AR-15-style rifle and high-capacity magazines, according to investigators. The massacre prompted Connecticut to enact a 2013 ban on such rifles, the same statute now before the high court.
Jennifer Hensel, whose 6-year-old daughter Avielle Richman was killed, was quoted in the families’ brief describing the multiple gunshot wounds her child suffered. She called the matter a “moral imperative,” urging authorities not to allow more bloodshed from assault-style weapons and emphasizing the duty to protect Connecticut residents.
A separate brief from Sandy Hook Promise, the gun violence prevention group founded by Newtown families, recounted that 6-year-old Dylan Hockley was shot five times. The filing said the impact of these weapons on children is “catastrophic and obscene.”
Nicole Hockley, Dylan’s mother and a co-founder of Sandy Hook Promise, asked the court to weigh children’s safety. “I know firsthand the devastation a semiautomatic rifle can inflict in minutes,” she said, adding that the consequences for children and communities should not be an afterthought.
Sandy Hook families at center of Supreme Court test
Gun rights advocates say they sympathize with victims’ families but argue that restricting lawful gun ownership is not the answer. They contend that school shootings persist despite bans on so-called assault weapons. Konstadinos Moros, director of legal research and education for the Second Amendment Foundation, a plaintiff in both challenges, said the focus should be on effective school security to deter and respond to attacks rather than banning a type of firearm.
The Supreme Court, which has expanded gun rights in recent terms, agreed in June to take up the appeals over AR-15 and similar semiautomatic firearm prohibitions in Connecticut and Cook County, Illinois. Lower courts have upheld both measures, and Cook County’s ban dates to 1993.
Comparable laws exist in roughly a dozen states, including in major cities such as New York, Los Angeles, and Washington, D.C. A federal assault weapons ban expired in 2004, and while efforts to renew it have followed mass shootings, states have continued to pass their own restrictions, including recent actions in Virginia and Rhode Island.
The cases mark the latest major gun dispute to reach the court since a 2022 ruling broadened Second Amendment protections and spurred a new wave of challenges nationwide. The court has said firearm regulations must be consistent with the nation’s historical traditions, a standard that will shape how the justices assess the rifle bans.
In the wake of such incidents, debates over firearms policy often become central issues in election seasons, shaping how citizens think about why voting is important and what kinds of laws they want their representatives to support.
The U.S. Supreme Court will now decide how those legal standards apply to state and local assault weapons bans, a ruling that could have sweeping implications for future gun regulations across the country.
