I was actually very impressed with the attitude and behaviour of most of the students at the march. The BBC quickly stopped using the clip of the students who were being interviewed while the trouble was taking place.(Wonder why?)
These students were very eloquently explaining that they had nothing to do with the trouble, and that this was not only unacceptable behaviour , but was counterproductive. An anarchist shouted something at them as he walked by and one of the young men called him back and challenged him about his behaviour. He asked if he had seen the policewoman being helped away from the scene with a bleeding head, and asked the yob if he really thought that was a good way of expressing an opinion and being taken seriously.Fair play to him. The yob quickly drifted away after being made to look completely stupid and immature.
I'd be interested to find out if those people causing the trouble had anything to do with higher (or any) education at all. I would be surprised.
