True it is a fruitless discussion as none of us can influence any outcomes but the consistency of the application of the laws of the game must be as frustrating for the players as it is us fans.
As a_a says, it isn't so much any injustice (or not) on a single incident but the fact so many other similar incidents get very different outcomes. In the Wales game North I think it was completely upended someone, legs up in the air, down on the head and neck yet no-one even so much as mentioned it. Common sense would say there was nothing in it but the law doesn't say so.
On other law related stuff, Phillips put the ball to the second row in half the scrums as did SA last week yet this is supposed to be one of the big crackdowns. I think Phillips only got pinged for it once.
I felt sorry for the Argentina forward who tackled Phillips when he had his hands on the ball and gave away a penalty for offside. Phillips did have his hands on the ball, the replays showed this and the Argentina player said this. The referees reply wasn't to ignore it or march Argentina back 10 for back chat, instead he said something along the lines of "I don't care if he had his hands on the ball, I don't want you taking any chances, don't come round in future"... basically giving Phillips as much time to fanny around as he likes in the future. It would be nice to see some of the referees less involved as personalities but more as enforcers of the law.

Carter also looks to have aggravated his long standing Achilles injury which can't be good
