On January 6, Breitbart News reported there were 21,093,273 background checks for firearm purchasers conducted in America
in 2013. And while this number of background checks represented a record, we explained then that the number of guns
sold could be many times higher. That is because background checks are done on gun purchasers, not on the number
of guns being purchased.

For instance, if everyone who went through a background check then purchased three guns, the number of guns sold in
the retail market alone would have been 63,279,819. That's not even counting the number sold privately.

And what happened as all these guns came into private hands? Violent crime and property crime fell.
