That question was asked of me on FaceBook.
As somebody who has served in the military, I understand a little concept called “opsec”. The things I have been talking about (how an actual insurgency would go in the US; hint: it wouldn’t be like Gettysberg with the government on one side, the “rebels” on the other and they shoot at each other until all the rebels are dead or fled) have stemmed from fairly orthodox Co-In strategy and tactics. (If you haven’t read “Eating Soup with a Knife” I highly recommend it–I think the author does not give sufficient consideration in his discussion of the Co-In failures of Vietnam to the fact that we had both an insurgency and a conventional war running in parallel, but when you compare the lessons he points to from Malaysia and Vietnam to what people are advocating in disarming the American people, you see why the “the military has fighters and drones and tanks and…” is such a ludicrous argument).
But that’s not the question one should be asking. The correct question is what the government is going to do when faced with massive non-compliance to bans? We’re already seeing that. Connecticut’s “assault weapon ban”, New York’s “Safe Act”. The weapons turned in, surrendered, or disposed of were orders of magnitude fewer than those believed to have been present in those States. The FFL background checks that would be required for any transfer out of State, any legal tranfer out of State. So either people kept their now-banned guns or they transferred them illegally–either way, non-compliance with the law. Some States’ bump-stock ban? Same thing. Zero surrenders.
So what is the government supposed to do in the face of massive non-compliance? Door to door warrantless searches? After all, the vast majority of guns aren’t on any kind of registration (and that’s why we oppose registration so strongly). You might be able to get probable cause for some searches but not for anywhere near all. And when you start making those warrantless, house-to-house searches? We’re already getting grumbles about innocent people hurt and killed in “no-knock” and other searches where there is a warrant. How many people will be killed by trigger-happy jackboots from those warrantless ones?
What do we call nations that do that kind of thing? (Hint: it’s not “bastions of liberty”.)
There is simply no way the government could even begin to take even a large percentage of the guns from the American people without becoming the very tyranny that justifies armed revolt against it–not just justify it to gun owners but justify it to a lot of the police and military who would need to carry out those orders.
And that’s leaving aside how truly ugly the insurgency that would result of that would be.
Good luck with that.
