Despite the fact that you're sourcing the Daily Mail, and that most of those pictures come from Newcastle (it's only to be expected there), that is pretty shocking.
I had very few problems on my NYE in Nottingham. A barman tried stealing money off me, but I collared him. No violence though, and a relatively low police presence in the city centre.
When you work in a nightclub, you see this sort of thing going on all the time. I'm not condoning it, but it is indicative of our society as a whole, and that combined with the fact that people who don't normally go out at will be out on NYE drinking more than they can handle makes it that much worse.
