Agree. No free man should be restricted or registered. Any man too dangerous to own a gun is a man too dangerous to walk the street.
I would suggest that some of whom you speak might even seek out jobs related to arms, such as police, military, government alphabet bureaucracies, National Guard, Drug gangs, Street gangs, “the mob”, and since it is just about impossible to know just who is “too dangerous” God created the second amendment.
We the people are the ultimate protector of human rights enumerated in that God Blessed document and Government is the fox in the hen house attempting to strip us of the means of protection, while acting as something other than the furry long nosed critter with four legs and a very bushy tail that will see to it that no chickens survive.
