I could be wrong here but i thought they passed a bill a few years ago that required all firearms sold at sanctioned gun shows to be registered to the new owner? Doesn't that require a background check? I could be wrong, either way this is just another unenforcable piece of legislation that will be extremely difficult to moniter. Unless the gun you are selling is registered to you LOL, this seems to be a bit of a stretch.
Although I dont necessarily agree with some of the liablity aspects of this new legislation, the principle of trying to keep people from selling guns to felons isnt a bad one. I think they are trying to prevent just anyone buying a gun at a gun show that couldnt buy one at a gun shop.
