The idea of youths being a problem here is a joke. I'm from London and recently had my front door kicked in by 4 teenagers while I was at work. One of them was on bail for some other misdemeanour. If a bit of 'hanging about' is the extent of the problem then I think we should be grateful! Trust me, there isn't a problem here.
I agree Hannah, We do not appreciate how lucky we are! Our youths are just trying to entertain themselves. A friend of mine was phsically attacked in the highstreet by a group of teenagers a couple of years ago but that is the only trouble I have ever come accross and you get the rouge teenagers showing off in any district. If we make decisions on appearances alone then we do have a problem as this is as antisocial as the behaviour that is being complained about.
