Quick history lesson. The National Firearms Act of 1934 was the first law to restrict weapons capable of fully automatic fire. Those weapons, along with certain other clases of weapons such as short barrel shotguns, became regulated under the act to require a $200 tax stamp and a lot of paperwork and approval to own such a weapon. The price was meant to be prohibitive - so that they could technically say it wasn’t a ban, but ather a tax - but you start putting a $200 (in 1934 dollars) tax on $10 guns, and no one but the rich can own them.
But still, at least tens of thousands of these weapons were registered, to at least tens of thousands of owners. I suspect these numbers go into the hundreds of thousands, but I don’t have the data offhand. For 52 years, no one ever used one of these weapons to commit a crime. A perfect record. If you were so inclined, you could say that gun control actually worked in this instance - who could own the guns was heavily regulated, and no harm was ever done with them.
(Some will claim that 2 crimes were committed with such weapons, but it’s misunderstanding. The 2 crimes involved were committed by police officers who got their weapons through their departments, which isn’t related to the same process that private citizens would get these guns)
So in 1986, a new proposal came up as part of the Firearms Owner’s Protection Act. Manufacture and registration of these fully automatic weapons would come to a halt. Existing weapons could still be owned, but no new ones could be built or registered, effectively banning them. There was no impetus for this ban. There were no big stories about misuse of the weapons. There were no crimes committed with these weapons. This was just a case of gun control advocates pushing any possible anti-gun legislaton that they could.
So let’s review. The weapons become tightly regulated in 1934. They have a 50 year perfect record - no crimes committed, no accidental shootings, nothing. The control measures, if you’re inclined to interpret it that way, worked perfectly. The legal owners of these weapons behaved themselves perfectly.
And yet despite this, they were banned anyway.
Gun control advocates aren’t interested in actually solving problems, nor preserving the freedoms of anyone. They are only interested in pursuing an agenda of pushing any restriction they can manage to pass, no matter how ineffective, nonsensical, or just flat out bad.
