I am just curious, and I am not trying to belittle anyone, but I'd really like to know just how the people saying "I will not comply" will actually not comply? Don't get me wrong, I HATE the new law. But I've bought and sold many used guns from good people on these forums, and everyone I've dealt with has been law abiding, so I'm wondering how it will work? Will gun sellers "Not Complying" not require a BGC and run the risk of being charged under the new law by an undercover law enforcement agent? Would people have to make a declarative statement like "No, I am not an undercover police officer" in order to buy a used firearm? Will gun sellers simply choose to not sell their used guns? I kinda think that putting efforts into getting the law revoked is a wiser use of my time than trying to figure out who and who is not an undercover LEO.
