Personally feel it has been dealt with very well by all, the RFL, St Helens, Wigan, Flower and Hohaia. A criminal prosecution would fail for a number of reasons. He was attacked first, there is very little precedent and Hohaia does not wish to take it further and this is key. If Hohaia and St Helens can be so eloquent and dignified about it why can't others?
You are missing the point. It doesn't matter to some extent if Hohaia and St Helens are dignified about it. That doesn't excuse what he did, that just shows that Hoahaia and St Helens both are accepting of what happened and are prepared to move on and be a better person and club respectively. In saying that, it doesn't mean that because they are being dignified that he shouldn't be prosecuted. My Nan's house was burgled a couple of years ago and it turned out the guy was a drug addict who stole some bits to feed his addiction. After about 6 months he had been in rehab and wrote my Nan a letter apologising and explained his circumstances etc. She didn't hold no grudges, she understood why he did it and wished him well. That didn't mean he was immune to prosecution though.
Hohaia was 'attacked' first, that is true. But there is no denying that Flower went too far. His second punch was beyond the pale. I'm not sure of the legal regulations but I think it's something to do with excessive force, you cannot injure your attacker if they are retreating or can no longer defend themselves. Hoahaia certainly couldn't do that.
