Please don't flame me I am not trolling. What is the basis of the anti's "Gunshow Loophole" argument? I've never been to a gun show but I find it hard to believe dealers are there selling guns without background checks. Are there a lot of non-FFLs there selling selling guns basically private party to private party? I'd just like to be able to handle that "Loophole" nonsense with the truth. That billboard in Boston seems to be the Gospel to the antis.TIA
