It also has a management problem. Trying to dump an incident off on a few cops doesn't work. Each incident damages the whole department. We know how to achieve nearly zero defects in a factory. Every worker and every boss participate.
Responsibility runs up and down the line.
A defect, and how to avoid it, are everyone's problem. Honest measurement and constant improvement are the norm. They build morale and shared commitment to quality. Lectures, sensitivity sessions and cheerleading are baloney. Satisfaction comes from being on a high-performing team.
