You do not get to be Chief by being a good Cop. You get to be Chief by being a politician.
are you a law enforcement officer or have any kind of experience with this? are you speaking about all police chiefs whether this one/this community or whether a small town in north dakota and so-on?
I had 35 years in Law Enforcement when I retired. There might be a very small number of Chiefs somewhere who got their job by being a Good Cop. I've just never known one or met one. One of the best Cops I know, never worked for him but know him, was just passed over for a Chief's Job. He's a damned good Cop but a poor politician. He just couldn't kiss enough butts to get the job.
You know a Good Cop who's a Chief. Let me know I'd like to actually see such a thing.
