Mrs Magpie is right, I think, that CSO's *can* make a difference. I live the other side of Ed's estate, on Railton Road, and we've had intermittent outbreaks of the same sort of trouble, albeit at a *much* lower intensity. But the summer passed off without major hassle (only a few instances of kids and teens terrorising residents with bottle-throwing or vehicles with stones), thanks, I think to the activities of the CSOs.
Thing is, there need be no mystery about who these kids are, and who is responsible (in law) for them. They are children, after all, that people see going to school and coming in and out of their homes. Once folk understand that the kid's lives are *not* going to be ruined (eg by a criminal record, or by being caught up in the Courts system generally) then they are generally OK-ish about trying to keep the kids out of trouble. Even crims don't always want kids to go down the same path as themselves. That's a losers' game, innit.
So the fact that the same old shit continues to go down on the same, relatively small part of Coldharbour Lane speaks volumes. Either the message is not getting through that CSOs have a mission to keep kids out of trouble; out of the Courts; and ultimately, out of jail. Or (possibly as a consequence of a failure to get that message across) the kids are not being identified; or the visits to the parents' homes are not being made; or effective help is not being offered. It's possible some of the kids come from hard-core criminal families, which does makes intervention rather difficult. But I doubt very much that is true of them all.
And it's no joke. Little shits out of control grow up to be big shits out of control. Kids stoning a shop show older folk that the coast is clear for other, even more violent fuckries. We just don't need that -- and the kids could do a lot better for themselves than to grow into depraved predators, and cannon fodder for the prisons.
Somerleyton Estate and the surrounding area is one of the nastiest, crime-ridden places in England. But it does not have to stay that way.
