Which is why none of my guns are registered and never will be no matter what law they pass....
In this day and age, the so-called legal system has morphed into a weapon of abuse to manipulate good citizens for the gain and power of corrupt politicians. This is why we have selective enforcement of the law and the rule of law has become a joke. 10 million criminal aliens run free while citizens the ruling class progressive thugs view as problems are stuffed in cages like animals and have their property jacked in the name of justice. Organized crime has simply taken over as the majority of decision makers and US citizenship has been grossly devalued.
Steps to locate your guns:
Contact manufacturer and force them to give up lists on who they shipped guns to. (This info is required by law)
Contact retailer and force them to give up lists on who they sold guns to.
Contact owner (you) and threaten them until they comply. This is what other dictators have used.
The loophole for owners is that they can get rid of their property as they see fit. You can put a blowtorch to all your weapons (hypothetically) and no one can say anything about it. “Sorry Mr Confiscator, I destroyed/threw away that weapon two years ago”
I think that all that is needed is if you want to buy a weapon that you should be required to show proof that you attended a firearms safety course.
