alt Hacker News> Legally buying guns in the US come with registration of serial numbers, names, and addresses.
It is illegal for the government to make a registry of gun owners. There is an electronic check to clear you as a legal gun owner but there is no registry.
It’s only theoretically non searchable, IIRC each submitted document has to be OCRed every time a search is ran on the documents, and this is enough of a legal fig leaf to qualify it as not a registry. A sizeable GPU farm would make this basically a moot point.
