the linesman could not see because of bodies were in the way, the ref was not sure- so the decision must go in favour of the defending team
That photo does not show the ball crossing the line, you could only tell properly if the photo was inline with the posts, the perspective of this picture can trick you. If you look closely you can see the shadow of the ball on top of the line.
For me, there is no argument. Goal-line technology HAS to be brought in. As in both rugby codes, a television match official should have the job of reviewing all the video evidence from all the angles until he is sure one way or the other. Any doubts remaining and the goal is disallowed and the game restarted with either a goal kick or a corner, depending on who last touched the ball. Time should be added on according to how long the decision takes. I know all that involves stopping the game, but it isn't the sort of thing that happens very often, so it shouldn't be a hugely disrupting delay.
No from me . Mistakes happen , part and parcel of the game IMHO . IF this is brought in , it will be the thin end of the wedge IMHO .
