The point, IMO, is that Tiger most probably saw the ball move. High def cameras aside, Tiger had the very best view of the ball when it moved (and it DID move). Otherwise, why would he stop trying to move the stick? Why? Because he saw the ball move.
When they first confronted him, he denied that it moved. When they showed it to him, he still said he didn't see anything. Then he said he thought it oscillated. Did he think it oscillated when it first happened? If so, why didn't he say that when they first confronted him with it?
Circumstantial, I know. I can't know what he was thinking. But we've been here before with Tiger. And it's not like his life story is full of integrity anyway. I gave him the benefit of the doubt at the Masters (although I thought a player with real integrity would have DQed himself instead of taking their profferred out). I feel sorry for him that this stuff happens as the result of him being under a microscope, but nobody should know that better than him. IMO, he figured he was far away from any cameras in this instance, n the woods, but he should know better. He can't get away with anything, so he shouldn't even try. And, in the end, the point is that the ball MOVED! Call it, take the penalty and move on.
I have to agree that part of the issue is Tiger's integrity and that is no one's fault but Tiger's. I can still remember my Dad telling me "if a man will cheat on his wife he will cheat you too". Of course people can learn and change but once you break the trust there is always that little doubt.
