Cops and Vices

You open the door to your office — the creaking noise grates in your ears.
You sit down at your desk and open a new case file. The title: Cops and Vices.
Details:
Police precinct, routine work.
The city’s main police department is starting to receive numerous complaints regarding the methods officers from this precinct use to handle cases.
One of the complaints, for example, mentions that officers use unconventional ways to solve crimes — in one instance, an officer received information about criminals’ next steps in exchange for “certain favors,” instead of treating the informant as a suspect and interrogating them formally.
There are also reports suggesting that interrogations are conducted in very extravagant ways.
It’s worth noting that the department is functioning effectively, handling and closing cases with consistent success.​
