From reason.com:

In five years as the head of the New Brunswick Police Department’s Internal Affairs Unit, Sgt. Richard Rowe managed to thwart 81 investigations according to a grand jury indictment. The former New Jersey cop is accused of falsifying, hiding, removing, and destroying files related to the investigations.

Apparently, Rowe’s world came tumbling down when he covered up for two officers who shot and killed an unarmed man under suspicious circumstances.  After a public up-roar ensued, it was discovered that the two cops Rowe protected had been “investigated” by IA nine times before the shooting, none of which resulted in any finding of fault.  As usually happens in cases like this, city and police officials will eventually act when public pressure makes it impossible to continue looking the other way.
