I hate that I'm typing this...
People need to start buying weapons right now. It's not that I think we're at the "take up arms" phase. It's that I think we should be ready before they keep us from being able to.
With all the shit they're pulling with federal databases, I expect people are going to start being added to NICS (background check database) for political reasons.
When you get a NICS denial, there's no explanation of why it's was denied, but you can't buy a gun.
And it will alert the FBI that you tried.
