And, J. Edgar Hoover didn't keep files on regular Americans who hadn't broken the law. If there is a Form 4473 executed as part of this, the law says the seller has to maintain a copy of this in a fireproof safe for 10 years. Federal law prohibits any registration
Yes, there is a law against it but that has not stopped ATF from visiting gunshops and asking for copies of their Forms 4473 - this is documented.
You are so very trusting of the government that is preparing to enslave you and you don't even know it. You believe they will obey the laws which they have clearly shown they will not. Universal checks requiring paper documentation make registration, through some concocted emergency action, available to the government - they know who has what and that is REGISTRATION.
Registration is just Confiscation unexecuted, again on the pretext of some BS emergency like the police actually did in New Orleans following Katrina even though it was egregiously and patently illegal and proven so afterwards.
If your argument is that the gov’t will do what it wants regardless of any law prohibiting registration, then, pardon the phrase, what difference does it make what the law is?
