You know...there needs to be a federal mandate or somesuch that allows, upon proof of irreparable corruption, entire police departments to be completely purged and replaced. Kind of like how you do for the Black Hand in Oblivion; there's a traitor in your Sanctuary, but don't know who it is, sooooo your boss tells you to purge the place of all life.
Like that, but with less killing and more dickheads being slapped with so many fines, they'll be bankrupt for the rest of their lives.
