Agree!  It's too bad in many instances that people who are totally psychologically unfit for serving in the role of police officer are hired for the job.  And you are correct that this problem occurs because we have chief of police that are also unfit to serve in that role.  There's an old saying, "The reason we have bad generals, is because they were promoted from bad colonels.  (Ever time I spell Colonel, I want to spell it like I say it "cernel, or cornel". I have to think of how Lebeau from Hogan's Heroes said it to spell it right)  But, I think also that we get our impressions of police from news reports, and that it may help of we each offered to do a ride along with a policeman to get a true impression of how they behave against real world circumstances.
