ProficienRifleman is exacly right! here is no reason for background checks for Privae Sales. That is why I was mystified when John McCain introduced, on his own initiative, a gun show Bill several years ago. The operators of the Gun Show would have been required to ensure, under federal penalty, that NO firearms were being sold, private or not, without a background check from the government. The most obvious result would have been fewer gunshows, but private gun sales have never been the problem they are made out to be, and background checks only confirm the legality of legal gun sales, and thus are pretty useless in lowering crime. And this has been confirmed even by surveys with antigun biases. In addition, the federal government has no juridiction on private gun sales. In addition, the anti's pretend that background checks and registration don't occur at all, and muddy the water by confusing periodit licensing and registration, as well as inspection requirements of people own houses by comparing those to Car registration.
I don't have problems with background checks in theory, but they are done in such a way as to infirnge upon the RKBA, do NOTHING about crime, and have the ultimate purpose of enabling a mass confiscation in the future.
