The "tHeYrE bUiLdInG A REGISTRY" argument is beyond tired. So they got 46 year old forms and... hang on isn't the dealer supposed to destroy them after 20 if they're still in business? So they got a list of 20 year old buys, every single one of which means jack shit since Florida doesn't have state-level registration. So they got a list of guns that the moment The Man (tm) tries to Come And Take Them they find out all of them have been "lost in a boating accident", sold or stolen.
It's the shittiest argument that just won't die. 4473s can't be used to build an actionable registry, and there are cheaper and more accurate ways to generate a "list of gun owners".
Story would be less suspect if the ttag piece hadn't included a bunch of outright incorrect information. But accurate or not, the embellishments made the story more provocative and they got their clicks. Which is all that really mattered in the first place.
