Speculations circle as to why the London riots have become so big, but the answer is quite obvious.

Most of the people who will be writing, speaking and pontificating about the disorder this weekend have absolutely no idea what it is like to grow up in a community where there are no jobs, no space to live or move, and the police are on the streets stopping-and-searching you as you come home from school. The people who do will be waking up this week in the sure and certain knowledge that after decades of being ignored and marginalised and harassed by the police, after months of not seeing any conceivable hope of a better future confiscated, they are finally on the news. In one NBC report, a young man in Tottenham was asked if rioting really achieved anything:

"Yes," said the young man. "You wouldn't be talking to me now if we didn't riot, would you?

Two months ago we marched to Scotland Yard, more than 2,000 of us, all blacks, and it was peaceful and calm and you know what? Not a word in the press. Last night, a bit of rioting and looting and look around you."

Eavesdropping from among the onlookers, I looked around. A dozen TV crews and newspaper reporters interviewing the young men everywhere.

There are communities all over the country that nobody paid attention to unless there had recently been a riot or a murdered child. Well, they're paying attention now.
