Quite accidentally, I learned this to be true. As a new first line supervisor, now many years ago, I saw patrol officers begin to work with much greater diligence when I was willing to get dirty with them. It was amazing what happened when I was willing to get off my duff and fingerprint a burglary scene. Whether a line supervisor or upper management, we can make a difference by getting involved with our personnel. As we call for them to follow us, we must be following something, viz.
True leadership is more than talk.
It is action.
