Hi MikeF, have a better idea of what you want now. A couple of thoughts. LE can not solve the gang problem....they can surpress it, but they can not solve it. Kilcullen said the best weapons in COIN don't shoot. Same is true in how to deal with Gangs. Or as it has been said on other threads concentrate on the environment(community needs) and you will take care of most of the gang problem. The few hard core ones that are left leave to LE to handle.
