Stop all infringement of our second amendment rights

The U.S.A is the greatest country in world, yes we have gun violence, which is almost all illegal guns. Yes we have mass shootings, which are ALL done by mentally deranged lunatics who indeed have real mental problems. But is the U.S.A still not the greatest country in the world? I'm going to be honest with you, a true free armed society (which is the only form of a free society) will always have gun violence along its fringes. It seems nobody wants to hear this but, the way to scale back these shootings are as follows. Hard nosed policing and enforcement of all existing gun laws in known high crime areas. Shall issue ccw permits for those who seek them. Documentation of people with known mental disorders. Documentation of people with mental disorders! Before we become 2nd best.
