Here is my view on Vaughan, it's unsurprisingly pretty simple and noting he has admitted that;
He ignored a NSW Health public warning, enforceable by police. He knew full well that it applied to him and his team mates and he thought he could "get away with it". That makes him doubly stupid, firstly for ignoring it and secondly there was no way he was going to get away with it. Everyone in that neighbourhood knows who he is and a team load of NRL players arriving at his house isn't exactly discrete.
He disobeyed the NRL player bubble orders, same as above, he knew it applied to him and his team mates and he thought they would "get away with it". He did this knowing the consequences, it's not like there weren't recent precedents of how the NRL would react.
He disobeyed the St George team orders, the ones on the whiteboard that are explained to the players at every training session. Once again he knew they applied to him and his team mates and he thought they would all "get away with it" by some miracle.
He encouraged his team mates to ignore a NSW Health public warning, disobey the NRL teams bubble orders and disobey their own club's orders. As a result he and his teams mates have forked out over $300k in fines and penalties. Nice to expose your fellow players to that financial cost.
His previous indiscretion in attending a cafe despite the same 3 orders applying are painfully similar, he knows the rules but he simply ignores them, he thinks he is above the rules that apply to everyone else and that he will "get away with it" somehow. The sexting scandal in 2018 was "covered up" by St George at his behest and he repays them with being unbelievably naive, totally stupid and shows a total lack of experience, wisdom and judgement by this time dragging 12 of his team mates into another of his failures.
I would add, so many times we have seen clubs cover up and/or ignore player indiscretions only for them to go on and commit further, in the belief that whatever they do will be covered up again and again. StGeorge farked up by their first effort in helping him to avoid the consequences of his actions, when it would have proven much more beneficial to teach the idiot a lesson the first time.
