The NRA can mobilize quickly. Guns are big business, something not often pointed out. The media usually interviews the lone gun shop owner, like a Mom and Pop operation, when a massacre happens. Yet, there are more gun shops in the USA than there are McDonald’s and Starbucks combined.
The NRA really represents gun manufacturers, not the gun shops nor the owners of guns. Those are their customers. In an analogy, it would be like Walmart saying they represent their customers. They don’t. They sell their product to their customers. Beyond that there is no relationship.
That the NRA advertises for gun manufacturers via Madison Avenue tactics that bring in the fear factor of dying if you don’t have a gun to protect yourself or your family, or if that doesn’t work they invoke infringement of the Second Amendment, in other words, nobody should take away your right to defend yourself, should come as no surprise, since in the USA, gun manufacturers cannot advertise their products on T.V., radio, newspapers, etc.
However, the Second Amendment to the Constitution of the United States only guarantees the right of a well-regulated militia to keep and bear arms. It does not guarantee the right of hunters to keep and bear arms, nor of individuals, who are not a member of a well-regulated militia, to keep and bear arms. The Second Amendment also does not protect the right of a well-regulated militia (nor anybody else for that matter) to kill with those guns–only that they can keep and bear them, should the need ever arise to protect the security of the State (meaning the USA).
