Infiltration
Their first target, the prodigal son of the elder has one routine every day. He would go to a bar and gather along with some of the lackeys of some moderately powerful and rich people and drink with them while all of them try to kiss his ass so that he could feel better about himself.
That is the only thing that can be remotely considered as a routine. The rest of his day is completely unpredictable.
The Enforcement Department is a special department. The City guards are responsible for stopping the crimes and regular patrol while the Enforcement department handles all the matter regarding handling the criminals, bringing them to trials or even sometimes delivering immediate punishments.
They are also responsible for investigating the internal affairs and workings of the administrative departments.
They don't move in the public eye that much, except for this prodigal son.
