The context in which the second amendment to the US Constitution was written no longer exists, rendering the concepts contained within it out of date.
What is present today is a unwanted cycle of violence.
This outdated amendment holds this nation in a constant perceived state of fear and distrust that grows in the susceptible minds into a larger cycle of violence.
As currently interpreted by the Supreme Court of the US, see link above, the right to keep and bear arms has been transformed into a violence inducing feedback cycle.
A violence reducing feedback is the reduction of number of arms, and or arm lethality.
Minimal violence is achieved with minimal numbers of arms.
