One of the four people killed in a mass shooting at an Arkansas grocery was a 23-year-old nurse who was shot dead while treating another victim, police said on Sunday.

"Instead of fleeing the store, she stopped to render aid in one of the most selfless acts I've ever seen," Colonel Mike Hagar, director of the Arkansas State police, said of the nurse, Callie Weems.

A shooting outside a grocery store in Fordyce, Arkansas, on Friday around 11:30 a.m., left three people dead and eight others wounded, Arkansas State Police Secretary of Public Safety and Director Mike Hagar said in a Friday afternoon press conference. 

Two law enforcement officers were among the wounded, but their wounds are non-life-threatening, Hager said. 

The shooter is in custody after exchanging gunfire with state police. 

Hager said the victims' wounds range from non-life-threatening to critical. 

Multiple people were reportedly injured Friday in a mass shooting outside a grocery store in Arkansas.

Eight people, including one police officer, were shot near the Mad Butcher in Fordyce around noon, the Southeast Arkansas Times reported.

The Supreme Court’s conservative supermajority carved a huge loophole into the federal prohibition against machine guns on Friday, striking down a bump stock ban first enacted in 2018 by the Trump administration. Its 6–3 decision allows civilians to convert AR-15–style rifles into automatic weapons that can fire at a rate of 400–800 rounds per minute. One might hope a ruling that stands to inflict so much carnage would, at least, be indisputably compelled by law. It is not.

The Supreme Court’s decision invalidating the nationwide bump stock ban ignited a firestorm among Democrats and gun control groups that have long maligned the device used to perpetrate the nation’s deadliest mass shooting. 

The groups expressed worry about not only the impacts of lifting the ban, which could trigger a booming rapid-fire marketplace, but also the other gun cases that remain pending on the justices’ docket. 

The Supreme Court has struck down the reclassification of bump stocks that was promulgated by the Trump administration back in 2018. As I noted earlier this year, this was not a Second Amendment case, but a statutory case, and, as such, the question was not whether bump stocks count as “arms,” but whether the National Firearms Act of 1934 grants the executive branch the power to regulate them in the same manner as it regulates machine guns. As the Court makes clear, the answer to this is unquestionably no. In consequence, the regulation must fall.

An Austin gun shop owner succeeded Friday on a years-long quest to overturn a federal ban on bump stocks, winning a 6-3 victory from the U.S. Supreme Court.

Bump stocks are devices that allow semi-automatic rifles to fire hundreds of rounds in a minute. The court ruled the federal Bureau of Alcohol, Tobacco, Firearms and Explosives can not include bump stocks under legislation banning machine guns. The overturned ATF rule required owners of bump stocks to either destroy them or surrender them to the ATF to avoid criminal prosecution.

The U.S. Supreme Court on Thursday ruled that a bump stock does not transform a firearm into an automatic weapon, striking down a federal rule that banned bump stocks. 

In a 6-3 decision, Justice Clarence Thomas wrote, "Congress has long restricted access to "'machinegun[s],'" a category of firearms defined by the ability to "shoot, automatically more than one shot . . . by a single function of the trigger." 

The Supreme Court on Friday overturned a Trump-era ban on bump stocks, ruling that the Bureau of Alcohol, Tobacco, Firearms and Explosives exceeded its authority by determining that the gun attachments turn firearms into machine guns.

The case was decided 6-3, with Justice Clarence Thomas writing the majority opinion and Justice Samuel Alito concurring. Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson, the courts three liberals, dissented.
