Congressman Russell and Congressman Gowdy Clear-up Firearm Misconceptions - YouTube: Published on Jul 6, 2016 Discussion with Congressman Trey Gowdy on Firearm Facts during Oversight and Government Reform Hearing on Firearm Inventory and Control Practices.
Foreigners already may not purchase a firearm in the United States. There is no "Gun-Show Loophole" because ALL licensed firearm sales require a NICS background check. We know NICS background checks (established in 1998) are working because, in 2014, there were 8,124 homicides due to firearms. This is a 9% decline in gun murders since 2010. This also represents a 20% decline in gun murders since 2005, and a 50% decline in gun murders since 1995. Of the 8,124 murders with firearms in 2014,only 248 were with rifles of ANY kind. To put that in perspective, 435 people were murdered in 2014 with clubs and hammers and 660 were murdered in 2014 with hands, fists, or feet.
