Sounds like an overly cautious interpretation of the "Straw Purchase" law. I'm guessing Springfield Missouri was one of the target cities for the training of FFL's. I can see where your situation fit the "profile" of a Straw Purchase, however common sense failed to prevail. When I get some time, I'll do a little research on this one, you have peaked my interest straw hat. I will say that the intent of the law isn't bad. A couple of years ago, a straw purchased handgun form Georgia, I believe, ended up in the hands of a gang member in Omaha, NE and was used to kill a police officer executing an arrest warrant. However, in my mind two people at the gun counter that can each legally purchase shouldn't constitute the belief that a straw purchase may be occurring.
