On Friday, Supreme Court Justice Samuel Alito temporarily reinstated the Biden administration’s ability to regulate ghost guns — homemade, untraceable firearms — overriding a lower court’s decision to block the government from enforcing a new ATF rule nationwide. At issue is a new rule by the ATF that classifies “buy, build, shoot” kits as completed firearms under federal law, CNN reported, and requires that the weapons be marked with serial numbers, that dealers run background checks prior to sales, and that all manufacturers and sellers of the kits be licensed. The rule does not prohibit the sale, purchase, or possession of ghost gun kits.

Alito, who has jurisdiction over the lower court in Texas that issued the block, put the case on hold until August 4, Reuters reported. The justice’s temporary reinstatement came in response to a request from the Biden administration to block the ruling pending an appeal. 

As The Trace reported last year, shortly after the regulation went into effect, ghost gun dealers quickly found ways to skirt the rule, showing that the regulation may have little tangible effect on the criminal use of homemade firearms. A May 2022 ATF report found that ghost gun recoveries increased 1,000 percent between 2016 and 2021. Nearly 700 of the guns recovered in that time period were linked to homicides or attempted homicides.

The National School Safety Conference bills itself as the largest school security gathering in the world. Last week’s gathering in Las Vegas boasted 1,400 attendees from across the country and nearly 100 vendors. But school violence experts question whether the security products offered by the industry, many of which focus on identifying or slowing a shooter rather than prevention, are the right investment for schools.
