Looks like the hysteria was fueled by the idiot business owner to me. Instead of pointing out any gun sales were done through an FFL with fed background check and sticking to that, he focused on mysterious BS mumbo jumbo and his bad feelings about being connected to it all.
According to the article, he only sold magazines and a holster to the NIU shooter, none of which require FFL involvement. That the NIU shooter decided to order from this particular person can only be blamed on the media, for publicizing the fact of his relationship to the VA Tech shooter.
In my opinion he took a pro-active action in order to prevent future unwarranted and biased scrutiny into his totally legitimate business.......I commend him for his action.
