Just read this article by John Lott, that had a bit of information I was completely unaware of:

In any case, virtually everyone who is stopped from buying a gun is a false positive, a law-abiding citizen who should have been able to buy but was caught in the Kafkaesque type world that McClintock found himself in. It is something to consider as the Obama administration and Hillary Clinton keep pushing to use the "no-fly" for purchasing guns.
