i spent a day last year teaching some kids in Forest Gate (east of Stratford) music.
was struck heavily by the attitude there. some of the kids were up for learning something a bit different, but they were in the minority. most of them were incredibly cynical about life, they seemed to believe there was no opportunities open to them in life and just wanted to wind up the teacher and f_ck around as much as possible. they didn't really see any kind of future for themselves, but they knew they could live off the system to a certain extent, and they knew authorities didn't have any real teeth to keep them in check.
i would imagine its these type of kids doing the rioting. most of the ones i met had good hearts, even if they did want to f_ck around all the time. i am surprised its come down to this, but i think dmoney is right - they just don't care
