Let me see if I can paint the picture for you, Darlington, our local town about 15 miles from here, there's at least two pubs on each main street and there's three night clubs. Remember this is a small town. the local supermarkets sell cheap beer, lager and spirits so people get tanked up before they go out. They go to the pubs first as there is two drinks for the price of one 'happy hour'. Alcopops are also knocked back, as many as ten in a couple of hours. then everyone goes to the clubs, these are crowded, everyone is drunk and or stoned. The atmosphere is heated and violent, drinks spill so fights start, drunks are thrown out by the doormen, moe fights start outside.
Then it's kicking out time and hundreds pour out into the street, more fights of course, people lying all over the street in various states of dress, throwing up, pissing in the street and over each other, ambulance personnel trying to cope with the unconcious, police trying to stop fights.
Blood, vomit, piss and spilt alcohol are running down the gutters, there's people lying in them too. the doormen are trying to help the police who have got every body they have working, trying to get drunks into ambulances and police vans. Bottles are thrown, benches and rubbish bins ripped up and thrown anywhere.
A couple of drunks start fighting, their girlfriends join in then friends and it's a riot, bottles smashed over heads, high heel shoes stabbing, people being kicked in the head, stamped on. the police use batons, CS to break it up and start arresting. Cells however full up so they have to go to neighbouring towns.
And this happens two or three times every week in British towns and cities.
