With all the tech now days you would think that they would have a system that the second the ball crosses the line it would lock in all of the film. If their was a dispute they could go back and hit a putton they would play film from about three seconds before the ball crossed. The film would stop at the point the ball crossed the line and the ref could look at all the angles and make the dicision. If the call is clear than the system would just move on until the next TD.
