I think it's even simpler than you both describe tbh. Everyone involved were basically thick people the worse for drink at 3am.
Exactly the same thing happens night after night all over the country, being a football player isn't the critical element imo. In fact, in my experience, being well known usually means you recieve a fair amount of leeway.
People like Chubby Brown and other deliberately offensive comedians, as an example, aren't abused or attacked in the street. But, there's a major difference with some modern football players who deliberately flaunt their obscene, and in this case, undeserved wealth in peoples faces.
Let's be blunt, Shelvey is a shyte human being and a leech on the game, this proves it yet again. He's always bleating on about being a dedicated pro, and reformed character, but here he is disrespecting the club and the supporters.
And, even worse, reinforcing the outsiders view of the NE and the drinking culture. At a time when civilised people, with the wealth to be able to buy the club, are considering their decision it's the last thing you lot need.
No offence to you lads but it's already bad enough with all the various protests, death wishes, stalking, etc from the more visible of your supporters.
I keep being told, on here, that there's no reason why the mega-rich won't be attracted to what the NE has to offer ...
... sadly, for both clubs, this is often how outsiders see us and its not pretty.
