The difficulty with enforcing via AGs is that prosecutors feel the need to have a good relationship with the police for their other cases. You need an office who isn't going to be working with local and state cops at all, maybe a federal body?
Attorneys General are usually not states or district attorneys. That may vary by state — I’m not an expert in this… iv lived in Connecticut, Massachusetts and New York, where the role doesn’t include that so my perspective.
Point being, as much separation as possible from the police (or any) chain of command is essential. The Federal government successfully used independent agencies until the circus that came to town with Trump part 2 appeared.
