The problem with that is, the CONSTITUTION says, that the people have the RIGHT to keep and bear arms. NOT the privilege.
Having the government say that a license is required to own firearms, gives the government full control over who is allowed to have them and who is not. This makes it tyranny and nothing more.
All Americans will be required to get their license and declare their fire arms, registered or not, or face becoming a felon. We all know what the final step will be after this happens. Outright confiscation, because the government will know were all the firearms are. At least those held by law abiding citizens.
Hunting will also be severely controlled or banned outright, using natural population control methods to replace it.
And the ignorant people begged for it.
Looks like there are about to be millions of new felons then.
The first crime is expensive, the rest are free.
