Advantage during the game, not after

The problem here is that the Refs are very reluctant to issue red cards to players - they are fearful that they would end up the same way as Poite did after the Eden Park test.   Poite was forced by the IRB to take a six month break from reffing important tests.   That is why they tend to issue yellow cards during the match instead of red cards, They cannot be blamed for poor reffing in such a case - they have the excuse that they did issue a yellow card for the offence.
The Citing Commissioner is not under the same pressure - he can take a harsher action without any question about  his abilities.         

 Mike, you have stated above the pressure on the ref and understood but surely he can ask the TMO for the decision and take the heat off himself. Is that not what the structure is in place for ?
I smell a serious flaw in the current structure never mind absolutely awful TMO decisions, over the weekend.

 The TMO decisions this weekend was really BS in capital letters.   I can remember where a try was in fact scored and the first camera angle showed it clearly - the second and third angles did not show it conclusively.  The TMO had the second and thirds angles replayed and then came up with the answer that he could not see whether a try was in fact scored.   
The TMO's must also be under review by the Sanzar panel.  They too easily favour "the home town advantage rule" and not what actually happened.   I also noted that they are very reluctant to recommend a card and only after the ref said he intends to issue one - do they concur with his finding - you can clearly hear it on the discussion between the TMO and ref.  
On the other hand I can also remember where the TMO advised the ref to issue a red card and he clearly ignored the recommendation of the TMO.   

 Mike, agreed and thanks for your insight.
Staying with my original post, i still believe that foul play should be dealt with during the game and not after the game, to give the non-offending side an immediate advantage.
It does not help the opposing side playing against 14 men after the game is over.
