Seat belts took a long time (decades) to be accepted and used by the American public. Solving the gun problem in the U.S. will be the same.
We must immediately stop all production, manufacturing, possession of, selling, assembly of (ghost guns) assault-type weapons and their accessories, ammunition and parts except to authorized governmental agencies.
We increase penalties dramatically, minimum one-year mandatory jail/prison time for violations with very limited plea bargaining.
It will take time and the supply of these weapons on our streets will dry up over time. This is an ugly situation and requires draconian action. Now is the time to act decisively for our public safety.
