Criminal damage, arson, assualt - even attempted murder (throwing a fire extinguisher into the crowd from the roof). This is unacceptable behaviour.
I am disappointed that the police didn't have a grip on the situation.
The only good thing to come out of all this is that it will totally undermine support for the NUS and Labour. The new solution isn't perfect but takes all the important steps. It is a vast improvement on the current situation.
