Getting back to the topic, and in the interest of doing some reasonable and perhaps enlighted speculation on the causes of the London rioting, I wonder what the riots in London might have in common (if anything) with some of the riots in the US that I've had first hand experience with (refer to post #101).
I don't think, because of the apparently random looting, burning, destruction and violence, that it's primarily politically or economically motivated (I think that Darcus Howe is wrong in calling this an 'insurrection'), and from what I've seen on videos and read, the vast majority of rioters are young people.
So one might speculate that the primary cause is simply a venting of youthful energy. But why so violent? Well, if the majority of rioters are young people who have grown up in communities of relatively poor people where, among young people, 'gangsta' behavior is glorified, then it seems to fit.
Young people in general tend to be disciples of the church of what's happenin' now. Their life experience is limited, they're not particularly wise, and they're somewhat naturally rebellious (without any particularly well considered causes). So when word goes out that their community is hosting a riot tonight and they're invited, then is it surprising that a significant number of them choose to participate?
So, what I'm proposing is that the cause of the London riots is an inevitable consequence of modern urban demographics and youthful negative exuberance and opportunism. That is, given how urban societies are structured we should expect these sorts of riots from time to time -- especially if it's also assumed that there are ever present undercurrents of racial and ethnic tensions.
To quell these sorts of riots police have to be capable of anticipating them, and then simply flooding affected areas with extremely large numbers of uniformed personel on short notice.
The English authorities either didn't understand the possible and imminent dynamics of their communities, or they underestimated the consequences. Either way, they failed in their duty. Most of the destruction that happened didn't have to happen. It was simply, via ignorance or miscalculation, allowed to happen.
This isn't to say that anyone (other than the actual rioters of course) should be blamed for the London riots. We all function wrt some sort of status quo. But hopefully the English authorities will learn from this and thus take steps to minimize the probability that this sort of extensive senseless damage doesn't happen again.
