Regarding the Magistrate, doesn't where you can fight him depend on which entrance you come in through? I always read that if you came in through the back entrance he's initially just in that courtyard but flees to the position at the end of the dead side. If you come in through the main entrance and come through from the live side he can be fought in the courtyard just in from the rear entrance. Lockpicking or engineering charges required to get through the shortest route from the front entrance. Also read somewhere that if you were fast enough you could ranged pull him as he flees when you come in the back door.
