Nigeria has the police complaints response unit. They receive complaints, but generally it's complaints to sexual causes. Those complaints have not led to greater improvements for prosecuting officers when they've committed crimes.
There's also the police oversight body known as the Police Service Commission. There have been a lot of challenges. As a commission, it lacks a lot of power to actually take cases of discipline and prosecution of officers independently. It's often headed by a retired police commissioner.
We believe those are some of the challenges those units have.
