abajaj11 - my answer is a resounding NO, but they already have that - perhaps just not specifically within POTUS or DOJ. Every time you fill out the form you write in your address and the seller calls (in my state the FDLE) and runs an FBI check. Do we honestly believe that the BATF and the FBI don't already know where we live and what we own? The only thing they don't have is private sales, but I tend to keep what I buy so I'm not optimistic about the reality of the situation.
Let's say you buy a gun through an FFL. FFL keeps a paper copy of your 4473 for 20 years. Paper copy is not given to DOJ. BATFE can come in and request a copy under exceptional circumstances usually involving a federal crime or some national security deal i think. NICs checks are never stored.
So as of now, Feds cannot keep a database of sales through FFls, that info only resides with the FFL. There is a paper trail in the form of the 4473 copy, but only stored with the FFL for 20 years. If the Feds were secretly keeping copies that would be HIGHLY illegal and grounds for very very long jail sentences for the FEd officers involved.
Now, let's say you live in a free state and can sell your firearms Face to face . So you do that, and now there is no record of who owns the firearm. You can sell ALL your firearms face to face and now there is not even a paper trail of those firearms.
THis is the situation today. And it is good because a potentially tyrannical government (the federal govt) has no business tracking who owns what.
2A was created to protect the states and their residents from a potential central tyrannical power with a standing army, aka in today's lingo: the Federal government!
Not to protect the federal government in any way.
2A transfers NO powers on the federal government to monitor or track any gun sales. That would be like the fox guarding the hen house.
Now let's suppose UBC is passed by COngress. we can argue it is unconstitutional, and there is a slim chance current Supreme court will hold it unconstitutional but likely not.
I can guarantee you current POTUs and DOJ need one small bone from Congress and they will take it and run...they will take any new gun control measure from Congress to be a license to create all sorts of databases by executive order.
In my humble opinion, if UBC is passed, we have 3 months before national registration occurs and 2-3 years before we are effectively disarmed.
So it's not the UBC I am concerned about at all, it's what will happen after....
