“They” are already trying, one little tiny bit at a time. It will never happen in a scenario like this; there are too many firearms out there now. To try to confiscate in a situation like this would be a dream for some of the preppers among us, and a nightmare for most gun owners like me.
The absolute last thing I want to do is go down fighting, but I will if that’s the only choice. “They” know that, which is why it will never happen this way.
