Don't know about BlueLou but I went to Brann and to Firenze and yes there was a minority of people who you could say, let the side down.
I enjoy a drink like most people but some of these guys and a few women too, were so drunk they couldnt stand up. I averted my eyes

whilst a bloke who was very drunk pissed himself because he couldnt open his trousers in time. Bear in mind he was standing next to me in the corner at Brann. I don't have photos but yes, it did happen!
Violence? yes, at Fiorentina, some of our own fans had no regard for anyone, - push, shove and kick out. The cops were antagonistic in the extreme but some of our own idiots just wound them up which hardly helped. There's always two sides to the story and the authorities were not blameless but drunken idiots squaring up to police officers armed to the teeth was always going to cause a bit of bother!
Football games are not vicar's team parties, I don't have any sort of problem with the language or the banter but I don't expect to see the sort of behaviour I've seen at the away matches.
Funny how I never see it in the LGS where all the scallies (like me?) are supposed to be.
Having said all that it is always a minority who spoil it with their obnoxious behaviour. It's not clever to piss yourself and it's not clever to create an atmosphere of fear at the games.
If anyone comes on here and says 'if you don't like it, stay away', well, that's exactly what I've done, I didnt go to Liege because after Florence I said never again.
Is it right though that ordinary fans like me stop going because a minority of people behave like total morons? There's no excuse for it and eventually away matches will be no go zones for anyone who isn't into a good fight or getting totally smashed.
