Back to the main point; I have no problem with WR clarifying the incorrect decision that lead to the final penalty but they could have worded it so much better. How about the following;
"With hindsight and the benefit of mutiple slow-motion replays that are not permitted to be used by the referee we can confirm a contact between the ball and a Gold player was not seen and this should have resulted in a scrum to Gold rather than a penalty to Gold. At live game speed with so many players in proximity to the ball and rapid changes of it's direction this omission by the referee is completely understandable ; no blame is attributed to the referee and he correctly applied the laws of the game in the situation as he saw it. Players make mistakes throughout the game, many players are willing to deceive the referee, even cheat at times, so the missing of one contact between ball and player is not considered a serious failing notwithstanding the affect on the result of the game. In an otherwise excellent display this referee will sadly only be remembered by many for this one moment. Media commentators could take a lesson from the Scottish captain and coach in how to behave in moments of deep disappointment at losing such a close game they were never expected to be competitive in."
World Rugby should have acknowledged that the RWC protocol for use of TMO is rubbish, and they should have been using the protocol in use in SA, which would have allowed CJ to go to TMO..
