So 2 weeks ago:
Olakau'atu gets sent off 4 minutes after making what looked like a fairly innocuous tackle on Tolman where there appeared to be no contact with the head & is suspended for 1 game;
Tupou gets penalised for coathangering Ravalawa, stays on the field & is suspended for 1 week.
This round:
Kennedy coathangers Walsh & is sent off, suspension TBA;
Ramien makes contact with the head in a very similar tackle to Olakau'atu's (but contact with the head is clearly visible) & is binned for 10 minutes, suspension TBA.
Can anyone see ANY consistency here?
