As cops make friends in a new station those friends give them money.
They develop a girlfriend who has family. That family wants a break for their nephew who cant stay out of trouble.
Local hires already have family sometimes numbering in the hundreds.
It gives that family a lot of power if they have several cops on the force.At some point you get to be afraid of all memebers of that family since they can have you arrested or beaten anytime.
This is the situation all over the third world, esp Mexico and Columbia.
I think SP needs a private security company that is well trained and works closely with the police. Cant trust any particular officers competence or honesty? He has a boss who can fire him on the spot if the clients dont trust him.The boss has a strong economic motive to do this.
