I think you are being incredibly naive if you believe you can hide anything from this government. The have Google, Facebook and endless other social media sites working for them, plus they follow your purchasing. Do you buy cleaning supplies for the guns you have off the radar? How about ammo? Do you go to the range to shoot? Have you ever admitted to owning non-registered guns on any website? Of course you have. You just did. I am sorry my FRiend, but they know who has the guns or at least they have reason to suspect, which for them assumes you are guilty and until you prove otherwise you will be subject to their rules. I hate it, but I know they KNOW.
Then perhaps it is time to identify and neutralize THOSE WHO GIVE THE ORDERS. "Accidents" and disappearances would be a good start. Or we could wait until those they send after us kick in the door, and take a few with us in a blaze of glory...
