They won't take my guns. They might take the guns I owned before I died in a hail of gunfire and flash grenades but I will never surrender my guns voluntarily. I don't think they would be able to find enough LEO's willing to participate in rounding up guns in my area. They might import some but the ones here would not go along with a ban.
The government was very scared of the militias after Waco and Ruby Ridge. It was said earlier that Tim McVeigh never got much support. He never deserved any. Killing innocent kids pretty much killed the militia movement. But an attempt to totally ban guns in this country will bring a lot of people out of the wood work who would fight tooth and nail against a ban in this country.
In short you would have a Civil War with many of the federal troops not only refusing to fight their fellow citizens but also joining those citizens outright.
From what I understand Australia never had the same kind of gun culture we have in the US. And GB has been anti-gun for decades. But one look at the IRA will tell you it doesn't take guns to kill people. Explosives can be easy to make if you know how. Unless they ban gasoline and matches they will never be able to ban bombs in the US.
I don't expect any bans including bans of military type weapons. There was too much trouble the last time the government tried it. Since then gun laws have been relaxed severely. We've had the whole CCW movement since then and the Castle Doctrine movement after that. And the liberals have gone along with these things too. For example in Ohio, the governor just signed a Castle Doctrine bill that included many gun laws being relaxed. And that governor is a liberal.
We have had a lot of momentum in the right direction since the AWB. I think liberals realize they will just energize their opponents if they try to impose more restrictions. The Supreme Ct. also just gave us the decision we've been waiting on for nearly a century. They said the 2nd applies to individuals and not to militias.
Mo is definitely on our side right now. I think any attempt at turning Mo around will just make us stronger. They know it's a battle they can't win at the ballot box, in the courts or on the streets should it come to that. They actually fear a revolt. That's why they wanted the guns to start with. They won't do anything to risk starting one. It just ain't gonna happen.
