It’s a state crime, property theft. The fact that it’s a gun is immaterial.
The Constitution says no government confiscation of guns. Period.
So now you're forgetting about the literal words in US Constitution? That is the antithesis of your original argument.
So then how are these gun confiscation laws constitutional?
It's implied. It would be absurd if it wasn't implied. The gun was obtained by theft.
Fraud vitiates everything. Gun theft, presidential election theft, it vitiates everything! There is no Constitutional right to possess a stolen gun and all the rights that go with that gun. AND there is no Constitutional right to posses a stolen office of the presidency and all the rights that go with that office.
