(going back to the op) given that gangs have not previously been conspicuous in looting or taking on the police, it seems to me rather a large shift in practice for them to suddenly take the lead in looting and rioting, which is what i thought the quote in the op was at least hinting at. the range of people out in the week can be gauged from the court reports, and unless the gangs are better organised than seemed the case - and none of them got caught - i feel that they have been awarded too prominent a role in the debate.
i suspect there's been rather more anti-hierarchical violence going on than has yet been reported - some of you will no doubt recall the chronology of anti-state, anti-hierarchical violence from the mid-1980s. i'm not too sure the iwca were right on this one.
