The FBI said it doesn't know the scope of the problem, but the National Rifle Association says about 7 million records are absent from the system, based on a 2013 report by the nonprofit National Consortium for Justice Information and Statistics. That report determined that "at least 25% of felony convictions . . . are not available" to the National Instant Criminal Background Check System maintained by the FBI.
Fuck anyone who claims we need more gun control laws.
Seriously. If they aren't lobbying to fix NICS first, then they can literally go fuck their own faces.
