I really don’t think that the government understands how many gun purchases /trades are between private parties. Hasn’t the database that is used for guns bought from FFLs been overwhelmed lately? Imagine how overtaxed the system will become if every single private transaction went through the database as well. Buying new guns from dealers is fun and all, but most of the guns that I have ever known, as well as those of my family and numerous friends has been through private purchases or trades for services rendered. I imagine that this is not unique to my little circle.
Nor do they understand how gun shows really work. The objective of this maneuver is "to close" the much vaunted "gun show loophole".
Yet, around 90% of the sales at gun shows are thru federal firearm license-holders -- who, by dint of their license, must submit background checks. Only a small percentage of gun show sales are conducted by private supplers -- grandma selling the deceased granddad's guns, for example.
This is just another case of the federal regulators being ignorant of the market(and products) they are regulating. But every liberal is aware of "the gun show loophole", so it just HAS to be closed.
