re: So did the USGA basically say their Open Champ is a liar??

In any other sport that has any sort of video replay, the standard that must be met is "indisputable evidence". However in this case the standard is "probable". I think that's the real issue here. If you're going to go against a player's word that he didn't cause the ball to move, then the video needs to clearly show that he caused it to move. You can't just say that he probably moved the ball because we can't think of anything else that might have caused it (like maybe the greens being faster than the hood of a Cadillac).
