Well for me I just tried to think what would happen if a government authority on a large scale found out about the supernatural. Two answers came to mind: Destory it or use it. My suggestions were coming from the persepective of use it and isnt the lust for power a recurring theme in Dresden? A government official trying to milk the newly discovered supernatural community in his city for all its worth and control it. Doenst sound too far from the setting to me. The only leap is a council that is largely clued up and more awareness then Chigcago's council was part of Anclagon's original premise. If we accept that then:
-Harry already works with the Police Department. A white council wizard who obeys the laws of magic first but also is under the employ of a government agency. He is succesfull in helping the police department prevent further supernatural based crime, in my mind it is only the refusal of those in charge to admit to the existence of the supernatural that stops this from becoming a more common arrangement.

is a medical proffessional helping to heal wounds from supernatural based incidents. Is it such a jump to a researcher clued up on the existence of the red-court trying to find a way to help the infected?
-Weve seen how the Fae guard their own and there is a history in the folklaw that the White and Summer courts are based from of Fae guarding 'fairy paths' and places they feel belong to them, grealy interfereing with the lives of mortals who built houses or their own paths in the way. It'd be difficult but im sure that somoene skilled at understanding the complexity of the accords would be able to negotiate with them over this and we all know how much cities love to expand at the expense of the nature in the area.
-Im sure a clued in police force would be interested in the information being passed along

is a free holding lord and his people are protected under the accords. I dont see any issue with a government official singing up to protect his people and of course the flipside of having your people protected by the accords is negotiating through problems with other factions protected by the accords. Wouldnt you want someone already skilled at manipulating the law like a lawyer working to help find the (many) loopholes in supernatural law?
-The White Court already manipulate and infiltrate mortal positions of power to make things easier for themsevles. I could see a family appearing to comply with city council whilst trying to improve their own standing and swing the position of power in their favour.
