That film is set in my own neighbourhood in London - North Kensington, Ladbroke Grove, Harrow Road.
It's a very different Notting Hill from the one you see in Richard Curtis films.
Kidulthood is not really about bad kids.
Even the villain is clearly suffering from neglect and the absence of love.
The characters are simply children in circumstances none of us would want to grow up in.
Their reaction to those circumstances is not good.
But it is natural.
Crime, drugs, underage sex - this behaviour is wrong, but simply blaming the kids who get involved in it doesn't really get us much further.
It is what the culture around them encourages.
Of course, not everyone who grows up in a deprived neighbourhood turns to crime - just as not everyone who grows up in a rich neighbourhood stays on the straight and narrow.
Individuals are responsible for their actions - and every individual has the choice between doing right and doing wrong.
But there are connections between circumstances and behaviour.
So when you see a child walking down the road, hoodie up, head down, moody, swaggering, dominating the pavement - think what has brought that child to that moment.
If the first thing we have to do is understand what's gone wrong, the second thing is to realise that putting things right is not just about law enforcement.
It's about the quality of the work we do with young people.
It's about relationships.
It's about trust.
Above all, it's about emotion and emotional development.
If the police stand for sanctions and penalties, you stand for love.
And not a soppy love! I don't see anyone soppy here.
But it is about relationships.
It is about emotional security.
It is about love.
