They don't know that there are two types of sellers at gun shows:
1) ffls who do BR chks (most common) irrespective of where they do a transfer
2) private parties selling guns (ya can only sell 5 a year - over that, ya need a ffl)
these don't need to run BR chks ... its just a private property sale + whatever state/local reporting or documentary requirements are required.
So they are complaining about (2) - private citizens selling their own private property -- what, we cannot sell out own property any more? Piss on them. And who cares if a seller had a BR check--he ain't gonna have the gun no more, duh!
I understand the viewpoint but they don't understand -- its OUR PROPERTY - we can sell it if we want. At a gun show or elsewhere. It really highlights the bogus nature of BR chks ..
