You are utterly, totally wrong, and it shows your stunning ignorance of this area (as well as your utterly worthless Tory politics).
Tottenham has some of the poorest neighbourhoods in the country. To grow up here is to grow up without hope, without jobs or prosperity, in a community scarred by crime, drugs,gangs and despair, with a blatantly racist, brutal local OB, into disfunctional, impoverished families, with a feeling that gets stronger every day that no-one gives a shit about you, and that this society offers you nothing.
Sooner or later, that social pressure creates a breaking point - and this was it.
you EVER actually been to Tottenham, Giles? thought not. So please do not make these condescending assumptions about that community.
