Replay doesn't show a bite!

It in needles to say that over the past months there has been a lot said on the subject, on this specific incident , what screen was he watching? On the replays screened by SS1 there is no way that the official could by 100% that a bite took place? What he perceives is not relevant here,he must see the bite surly? I don't know what the answer is , we get controversial calls week after week and week after week Andre Watson backs his guys , wake up , the crowds pay good money to watch rugby not a linesmen wanting fame and as for WR , if that is all we have in the cupboard then Andre Watson has a major challenge
