If this does turn out to be a racist attack then the vast majority of our fans would be appalled and want everyone involved banned and the dealt with by the police however lets look at the two scenarios being presented.
One scenario is at a gathering of fans that wasn't pre-planned and included families, kids etc a couple of chaps turned up started having a pop at people and saying they had a knife, as multiple eye witnesses have said. Some people went to inform the police, others chased the group. The police arrived and dealt with the two chaps and a knife was recovered from the scene.
The other scenario is at the same gathering, someone persuaded two innocent chaps to turn up and start having a go at people. They arranged for some members of the crowd to go and lie to the police saying the chaps were armed. They arranged for a mob of fans (although some are claiming not actually fans but undercover police) to attack the group based on the colour of their skin, which would be unlike anything I have witnessed in 35 years of going to games. The mob were also instructed that during this racist attack they should make false claims about the chaps having knifes in case it was caught on video. They were conveniently chased to a location where a knife had been planted.
Which one seems more likely?
