After passage of GCA'68, there was a joke that the head of (then) ATTD called in agent Smedley and told him that there was a ship in Boston, the USS Massachusetts, that had a bunch of 16" rifles that had not been registered and were to be confiscated. Good old agent Smedley, eager to please, drove to Boston in his GSA station wagon to bring back the guns.
Sometimes, it pays to really understand the situation before taking action. (I didn't mention Iraq, did I?)
