The county will have to persuade the voters of Oregon to repeal the state anti-gun laws. The Second Amendment is pointed directly at the FEDS, not the states, despite what the Left says. The BIG issue is the feds have NO constitutional authority to interfere at all with state gun laws.
Section 27. Right to bear arms; military subordinate to civil power.
The people shall have the right to bear arms for the defence [sic] of themselves, and the State, but the Military shall be kept in strict subordination to the civil power[.]
Well they have a good start with their own constitution.
