My concern, with the double dip recession, benefit cutbacks and housing benefit reforms, lack of jobs and a growing young population in this city is that we will potentially reach a flashover point when citizens take to the streets to riot - not because of greed or opportunity or failure of the police to act quickly enough, but because they want to survive and live a life worth living, not one of poverty, social disadvantage and as a group to be blamed by those with wealth as being feckless, idle and a drain on society.
