I would say more like a party who undo's infringing laws.
Background checks for private party sales sounds good, but then you would need a registration to keep track of the guns. And that don't fly with many states.
they added universal background checks in oregon stating there were 10-20 thousand private sales a month. Several years later there are perhaps 300-400 a month actually checked.. Also extremely low denial rates with pretty much no arrests. Lots of non-compliance and it turns out only the really stupid criminals go to a FFL to complete their background checks.
At the same time they made the Curios and Relics 03 FFL illegal. Since I guess of all those crimes with WWI bolt action guns.
And then if you look at the actual records in the FBI NICS background check database these are the total listed records in Oregon by category.:
Felony: 2
Under Indictment: 0
Fugitive from Justice: 0
Unlawful user/addicted to a controlled substance 0
Illegal Alien 0
Dishonorable discharge 0
Renounced US citizenship 0
Restraining order for domestic Violence 0
Convicted of Domestic abuse 2
So despite making a law that all all private transfers are illegal without a background check, it turns out very few are bothering. And then, the background check database has a total of 4 felonies and Domestic violence convictions to check
On top of that, many of the counties that still respect the constitution said that they will not convict anyone if they dont do a private sale background check
another interesting fact. Wyoming only lists 7 (seven) mental health records in the background check database. Wyoming either has the most mentally stable people on the planet or the state is not actually reporting the records.
Even more interesting?? Wyoming has the least "mass shootings" in all of the US every year. They dont even bother reporting mental health disqualifiers and they have the least crazy people shooting up malls. I wonder why that is?
See why a universal background checks are quite dumb without a reasonably functioning background check database?
