Exactly. You rarely, if ever see middle-class suburban areas have the types of violent crimes occur in them. It is almost always the urban ghetto where most residents only know violence and don’t pay for their rent, utilities, etc. themselves so them make no effort to improve their neighborhood.
This usually ends in them demanding the police solve the problems of their crime ridden areas, while refusing to cooperate in any PD investigation.
Idle hands are the devil's workshop.
