I see no mention of systemic checks and balances or corruption investigation further than a couple of bad actors. So yeah cover it up replace it with something hopefully less corrupt, but not what needs to happen to prevent it from happening again.

I see the "federal investigation" as a systemic action, and I don't really see how disbanding the old department is a cover up, it's a pretty real consequence.

Consequence to who? Not the corrupt officers who weren't the scapegoat, all they had to do was re-apply for their old job.
