Please read this excellent post on the London riots from Penny Red.
I have thought a lot about the riots, about social exclusion, about the structural deficiencies and amorality of capitalism, but I lost lucidity sometime around the moment when I burnt the stock pot and, had we not had a smoke alarm, would have caught the house on fire.
The rioters, burning and looting and attacking police, did the wrong thing. They all did very wrong things. There is not a time to be listened to if you are dispossessed. You are always required to go back to the queue and wait quietly. Not everyone is prepared to wait forever.
