****...it will be nothing less than suicide by cop to do anything other than what you are told. ****
I always personally felt the way to confiscate arms is to go into a small town, declare that all guns must immediately be turned in on pain of death!
Then institute a house to house search, find a gun kill the owner.
Then roll on to the next town. You will then find most all the guns piled in the street.
Wives do have a way of convincing their husbands to do it.
This just pitted the feds against the "rest of us". It's already an us vs them thing with LEO and all the alphabet agencies that are Spec Op wannabees.
The real way of fighting this is having patriots in the agencies and operator communities. There may be some fratricide and THAT will be the MOST effective deterrent. Not open fratricide but even informational fratricide ... ambush, booby traps etc.
It's gonna get ugly, but I never expected to die crapping in my pants , lying in a bed all alone while someone rolls me over and bathes me.
You'll find the 10% who are non-compliant laying in the long grass along the roads between those towns, picking off the convoy.
That said, there aren't as many married men as there used to be. This side effect of the socialist-welfare state might have unintended consequences for the state's enforcers.
