This was not a dumb pointless soccer riot. It was provoked by the government violating the rights of the people. The people pushed back. Sometimes that turns violent. Sometimes it gets completely out of control. Sometimes it gets so out of control, that in the end the old regime is cast out and a new form of government instituted.
The French Revolution was no different. A bunch of hooligans mindlessly rioting and destroying things over some minor matter they should have just let go. But in the end, the king was dead, him and his wife's heads were cut off and spat upon.
This round the government got the upper hand. The people in the UK are not happy with how things are going. The revolution is not going to be this month, but it has started this month. The nation is already dead, having abused the people too long. Hard to say how much time they have before the final revolt, but it's obvious to this impartial outside observer that revolution is coming and the momentum is strong enough that throwing dissidents and fools in prison will only hasten its inevitable fall.
