I think the riots were provoked in order to push through unpopular policies. We've not heard the verdict yet on Mark Duggan, apparently Trident had been following him for months. From all accounts it sounds like he was a well-liked man in his local community, helped out with youth footie etc. Doesn't mean he was an angel but whatever he was 'guilty' of, what prevented him from being allowed a fair trial? There'll also be officers present at his funeral, I wonder for whose benefit.
I think most of the damage caused during the riots was allowed to happen. To prove a point. Why were no police seen to be at least attempt stop people stealing, petrol bombing cars etc. They were stood doing nothing, why no arrests at the time the riots were happening, why were they all in the days after?
Then out of nowhere the government talk of pushing through curfews, gang injuctions (whatever that is) and shutting down social networking sites. What do normal people think of this, is it a good thing? To me its says police state. Who's gonna take to the streets in the months to come? The unions, thousands of people that have lost their public sector job, people protesting for a new election, an anti-war protest (iran, syria anyone?). Perhaps thats when these policies will really come in handy, along with the ones Blair brought in after 7/7.
