Consider the possibility that it was not an accident at all, but rather an orchestrated attempt of anti gun zealots in law enforcement, the Feds and the media to promote gun show,and Second Amendment restrictions.
Does anyone who is from that area KNOW the person who brought the loaded gun? What was this person's demeanor? Did the media mention the NAME of the person who brought the gun? Might be interesting to find out a little more about him, or her.
