Mark Kelly, the husband of Gabrielle Giffords, purchased a .45 1911 and an AR-15 the other day: https://www.facebook.com/photo.php?....215073368547929.71130.163148530407080&type=1 First, a background check is a background check - they are all the same until you get into NFA items. Second, the only way to buy without a background check at a gun show is to buy from a private seller - someone who brings their gun to the show to sell. Dealers must still do background checks. The "gun show loophole" isn't a loophole, it just allows people to sell their private goods to another person without the government getting involved. Note: It is still a felony to sell a firearm to someone you know, or should have known, is not permitted to own one. Third, you cannot buy a firearm over the internet without a background check. It must be shipped to a FFL where a check is done when you go to pick it up. That aside, by buying the AR-15, he is either a hypocrite and a felon or just a felon. Hypocrite: He advocates for the ban of semi-automatic rifles, but he went to purchase the AR-15 for himself, got recognized, and claimed he bought it to give to the Tucson PD. Advocating to ban these rifles, yet buying one, seems a bit hypocritical. Felon: He intended to purchased the weapon to give to the PD, which may or may not meet the definition of straw purchase - also a felony, but he lied on the 4473, which is a felony. So, which is it? Either way now, he seems to be committing a felony by lying on the 4473.
