Local gov't trades reach and power for proximity and savvy. This manifests as fairly equal amounts of influence from each level of the "hierarchy".
I think it's funny that you would use torture as your example, considering that several municipalities (most infamously Chicago and its PD) have been caught torturing suspects and have been placed under federal watch if not control in order to curb their abuses.
What's important about federal oversight is that it is accountability. The ultimate fact is that few institutions, let alone local ones with limited budgets and moral hazards/incestuous conflicts of interest galore, are capable of effectively policing themselves.
