Judge Andrew Napolitano confirms that the ATF is stockpiling the personal info of gun owners.

Waiting for all the guys who insisted the ATF doesn't save this stuff to post on here

I don't think anyone's ever argued they don't save it. Especially anyone who knows how the gun business works. If you didn't know you would after sending in your records when you go out of business.

But compiling data on guns and those that bought them, 20 or more years ago in some cases, is a lot different than some imaginary backdoor registration scheme. If it's registration, it's the most fucked up way imaginable of doing it. Course, with our government, that almost makes sense.

ETA: Once again, they only get personal information and specific gun information from the 4473 (which could be a couple of decades old by the time they get it and get around to archiving it). They don't get gun information (specifics) from background checks...or back round checks.
