It would indeed be futile to take them on “full frontal”, because they have virtually unlimited resources.
If you fear confiscation, HIDE it. Keep some in your home for them to confiscate and “do their job”, and let them move on.
Then send the balloon up (short wave, whatever).
Organize resistance for the second wave, or pick a time to fight them on YOUR TERMS.
Fighting them on their terms will just end up losing one good resistance fighter (and a bunch of preps) that could have been used better later.
I know you are correct in what you're saying, but it still really chaps my hide....grrrrrr.
I would have a hard time living with myself if I allowed them to come into my home and confiscate my property, even though strategically it is the best move, still burns my a$$ though.
