Not really sure what your point is. I can't explain why Hanigan was not yellow-carded, i.e. it was probably worth a YC. I also cannot explain why Moody elbowing Beale in the neck, thus taking a player out of a defensive line, thus helping a try getting scored was not even deemed penalty-worthy. Oh, sure it got cited, but that hardly helps during the game. Similar, the French guy with the pulped face. Things seem to get missed, and/or dealt with variably. I guess, at least, Hanigan did get penalised.
