Here is what I would say to the BATF if they came tresspassing on my doorstep:
"Are you giving me an order to see my arms or even talk to me? If so, I charge $500.00 in Gold and Silver coin, per minute, for my time and my property. Just sign right here that you accept full commercial liability in giving me an order to do business with your corporation. I will also need to see your ID again and an address where I can send you your bill. "Just sign here and you can have all the access you like." "Payment is do at the time services are rendered, of course, I will give you 48 hours to get the Gold and Silver coin. You do have an oath of office to uphold the Constitution of the UNITED STATES, right?" "I accept your oath of office, sign here and come on in, its a pleasure to do business with you!"
Or, you could tell them about your "Constitutional rights" and see how far that gets you. LOL
And I would film/record the entire transaction, just in case they think they can not fulfill their contractual obligation to pay my fee.
It's just business, and the stories of home visits are true, I talked to a couple from Texas who had a visit from these guys because she bought 2 ARs at a gun show. They told her she did not meet the 'normal profile of an AR 15 buyer.'
If even 10% of the people charged them a fee for their orders, they would stop doing it pretty damn fast. Does it suck to be a US CITIZEN yet? Sovereignty is a wonderful gift, I thank our forefathers for creating a government with Laws to protect my Creator given rights.
You CITIZENS are in for a bad few years...
