I think this example and the one 2 years ago are far more extreme. Those people shouldn’t have even been there, the club specifically asked people not to go out and gather. Couple that with Liverpudlians are meant to be proud of their city, along with fireworks and the like leaves a sour taste for me.
For full transparency me and my wife went to Liverpool 9 years for our first wedding anniversary found it be a beautiful city and great people. 2 years ago as I said the place was disgusting after the football and on the evidence of that and last nights pictures I’d say it is in part a Liverpool fan issue. I’ve had the pleasure and displeasure of working in most cities and major towns in the UK so I’d like to think I have fairly unblinkered view of UK cities
I do take your point on a wider society issue but I don’t think that is the full story here sadly.
