i don't think they should be able to use that overhead shot as the angle of the camera may not be exactly overhead and would/could affect the decision. if it were slightly behind the ball it would make it look over the line, and if it were slightly ahead of the ball it would make it look short of the line. MM needs to protest that call on that basis so it can't be used again. it's not a fixed camera location so it should be void for this purpose...other things would be ok though, but not forward progress.
