This is not a Maryland problem but rather a Baltimore problem. Despite the state's existing age restrictions on gun ownership, male juveniles have wreaked havoc on the city, making it one of the most dangerous in the country. Maryland also has some of the strictest background checks in the nation, but that, too, has not led to fewer crimes. The real issue here is violent young criminals. Taking guns away from law-abiding citizens won't do anything to stop that.
A conservative activist Supreme Court has expanded gun rights to an unprecedented extent, forcing states to try and find workable solutions to the gun crisis in the US. A torrent of legal cases in the wake of the Bruen ruling has upended gun control as we know it, undoing decades of progress on gun control amid an epidemic of violence and mass shootings. Maryland should be applauded for trying to find a path forward to keep Americans safe.
