I think there has to be some commonsense in questioning, is it illegal, is it dangerous or could it be dangerous. In both Mason and Jorge it was embarrassing to see the penalty.
I watched the game Bulldogs V Titans .. wow the tackle on Brett Morris was DANGEROUS. A minimum of sin bin (but no). The refs have enough experience and knowledge to know what is dangerous to act on it. And if they get it wrong so be it.
There are always situations where it is 50/50 calls. eg the try scored off the kick that Snake stuffed up. Even though he was taken out after he tapped it with his foot, it was a great kick, good following up by Raiders, stuff up by Snake. It would not have been fair if not awarded. I go by the creed if it looks like a try or penalty it is. Mistakes will be made but that least in the long run the best team will win.
