I will not imprison members of the same party in the same cell block, let alone the same cell. If they are important prisoners, I will keep the only key to the cell door on my person instead of handing out copies to every bottom-rung guard in the prison.
I will not have captives of one sex guarded by members of the opposite sex.
When arresting prisoners, my guards will not allow them to stop and grab a useless trinket of purely sentimental value.
My dungeon cells will not be furnished with objects that contain reflective surfaces or anything that can be unravelled.
My dungeon will have its own qualified medical staff complete with bodyguards. That way if a prisoner becomes sick and his cellmate tells the guard it's an emergency, the guard will fetch a trauma team instead of opening up the cell for a look.
If one of my dungeon guards begins expressing concern over the conditions in the beautiful princess' cell, I will immediately transfer him to a less people-oriented position.
