Yep - manditory background checks (including father to son at the range) would stop criminals dead in their tracks = no approval, no BGs w/guns, right?
These studies imply that there are plenty of dealers/FFLs who do not do their job. That just isn't the case.
Seems it would be better to require background checks when transfering possession of a vehicle. Surely that would stop BGs from moving from point A to point B with such ease.
