"Gun control advocates argue that federal regulation of firearms curbs access by criminals, juveniles, and other 'high-risk' individuals. They contend that only federal measures can successfully reduce the availability of guns throughout the nation. Some seek broad policy changes such as near-prohibition of non-police handgun ownership or the registration of all firearms or firearm owners. They assert that there is no constitutional barrier to such measures and no significant social costs. Others advocate less comprehensive policies that they maintain would not impede ownership and legitimate firearm transfers."
