"Police expect a repeat of the riots that spread across England last summer and are concerned about whether they will have the resources to cope with more unrest on that scale, according to the findings of the most in-depth research conducted into the disorder."
As the overall situation of the young has declined in the last year, I think it is a possible scenario - not that last year's riot was only political, lots of young folks just used it as an excuse to do a bit of thieving.
If Cameron carries on like this we will have a huge number of disenfanchised young people who will want to smash something.
