Absolutely, it's easy to blame the police, because they are the ones we see. Having witnessed huge groups of fans at; rugby, motorsport and various entertainment events, nothing gets policed in the same way. But at the same time you don't see the same levels of disorder.
The reason Sunday required such strict policing isn't because there 30+ thousand going to the game and tens of thousands watching in pubs across the city. It's because of a few hundred idiots from both sides of the divide. The sooner these morons get banned from football the better. The minority of idiots at Middlesbrough, against Norwich and against the pigs, do not represent this great club. Ban the lot of them for life and stop them spoiling it for the rest of us.
For me the reason the Sheffield derby is so special is that my brother and some of my best mates are Wednesday fans. It's a sad state of affairs when friends and family can't go for a pre match beer together then go sit in opposite ends of the same ground. Sure I might shout abuse at them for 90 minute, but afterwards it should be back to boozer for more beer and piss taking.
I hope these hooligans realise that they aren't proper fans. That many of us hate everything they stand for, and are sick of them ruining games for us. Football is incredible, we all love our club, but if you can't be responsible for your own actions then stay away.
