In reply to Jim 1003:

I never said it was.
I said "there's nothing to do" is not a very convincing argument. Lack of things to do is not why there is a gang problem. It is other things. Lack of opportunity - real and perceived, social inertia - including a viscous circle of arms between the gangs and the police - all sorts of things.
The idea that there's nothing to do is preposterous. People may have expectations for more than there is, and may not be equipped to enjoy / engage with what there is, and gangs may hold more allure than other activities, but there's a lot of other stuff.
