Heavy handed policing and zero tolerance from the club have everything to do with how other fans behave. They didn't just wake up and decide one day to be a bastards about it. It took years of violence for the current state of affairs to evolve. It will not change whilst people condone, excuse and continue that kind of thing so it makes no sense at all to complain about injustice at the same time as attempting to justify hurling coins.
The above (part) post by Nibor highlights the hypocrisy of those defending violence in football, who then bleat on about how badly they are treated by the club, police and stewards.
I suspect many of those protesting about the dawn raids and bans being handed out, have indeed been involved in similar unsavoury behaviour. Can these 'supporters' not see that the legacy of years of thuggish stupidity has reaped today's environment.
You can only blame yourselves for making a rod for your own backs.
