An Alternative in Gun Control

The Second Amendment has the term “keep and bear arms.” It does not say ‘own’ arms.
This is entirely within the traditional view that the Amendment is primarily to prohibit the federal government from disestablishing or taking over the State militia.
When an individual was inducted into a government militia, he were expected to bring his own weapon or would be issued one. That weapon was his responsibility, whether kept at home or at the militia arsenal.
In modern times, State militias, commonly thought of as the National Guard, have issued weapons and do not allow private weaponry. But the National Guard is not really a State militia since it can be easily federalized.
The answer is for each State and each jurisdiction within the State to have the right and power to form a militia. Anyone wanting to ‘keep and bear arms’ would have to ‘enlist’ in that militia. Then the militia would be able to decide what weapons it will allow and refuse to induct those individuals who would be potential threats to a ‘well-ordered society.’ At the same time, there would be no requirement for a jurisdiction to have a militia or to require enlistment if it so chose.
This may seem to be convoluted and bureaucratic. But it is an American solution to the gun control/militia problem. It is both practical and obedient to the Constitution.
