The Supreme Court has struck down a Hawaii law requiring people to get permission to carry guns into places such as stores and hotels. The Thursday decision is the high court's latest ruling backing Second Amendment rights. President Donald Trump's Republican administration opposed the law, arguing that Hawaii had violated gun rights by effectively banning them from a wide range of places generally open to the public. Hawaii, on the other hand, said the 2023 measure was aimed at protecting the rights of property owners. The decision doesn't stop businesses from taking their own steps to ban guns on their property.
