A bowler throws a split (6-7-10). By the time he turns and walks to the ball return the 7 pin is gone. No one knows whether it not it was knocked down legally or knocked down by the pinsetter. The bowler proceeds to pick up the 6-10 spare. His team wins by 5 pins. After the game is over a bowler from an adjacent lane says to a bowler on the losing team, "You would have won if they had reset the 7 pin on that split, the pinsetter dropped it." After much discussion and debate it was determined that the bowler would have to shoot at the split. He did, he missed, and the results of his score and the game were altered. Was the right decision made? If not, what should be done now?
