So what it was miles away from where the shooting was
The NRA is all about selling guns to criminals. They will not stop selling guns to lunatics, felons, or idiots until they are forcibly stopped. All purchases (private or commercial) must include background checks and public registration.
Where does the NRA sell guns? What are their sales figures per year?
Do liquor stores close when a drunk driver kills someone? Do video stores close when someone makes a film that causes riots? Do book stores close when that pastor preaches hate against gays?
