The Supreme Court has ruled against a broad federal ban on gun ownership by marijuana users. The decision Thursday is the latest in a line of firearm cases from a court that has expanded gun rights. The justices decided unanimously in favor of a Texas man who argued that a law barring guns from anyone who regularly uses illegal drugs violates the Second Amendment. Justice Neil Gorsuch wrote that his opinion narrowly limits the government’s power to take guns away from drug users who aren't considered dangerous. The Trump administration had defended the law, but Gorsuch wrote that its core argument “fails under every measure."

Legislation in two of the nation's most populous states could force 3D printers to come equipped with technology blocking them from making guns. A first-of-its-kind law limiting three-dimensional firearm printing recently passed in New York. A similar measure is pending in the California Legislature. Both would direct panels of experts to come up with technological standards aimed at preventing guns from being printed. The actual blockade would take effect in 2029. Gun rights groups and digital privacy advocates both have raised concerns about the legislation. Others have expressed skepticism that the printing blockade actually will work.
