Recent legal developments concerning gun rights in the U.S. have significant implications for firearm regulations. A Kansas court ruled that machine guns are protected under the Second Amendment, asserting they are 'bearable arms' and placing the burden of proof on the government to justify any bans. Meanwhile, the Firearms Policy Coalition has petitioned the Supreme Court to review Maryland's ban on semi-automatic firearms, arguing the ruling upholding the ban misinterprets Second Amendment protections. Additionally, the Eighth Circuit upheld a decision stating Minnesota's restriction on handgun carry permits for 18-20 year-olds is unconstitutional, reinforcing that the right to bear arms extends to younger adults. These cases reflect a broader trend of challenging gun control laws post the landmark Bruen decision, which requires historical justification for firearm regulations. As these legal battles unfold, they may reshape the landscape of gun rights across the nation.
