The fact remains: cops (and cop supporters) are proud and that's not necessarily a bad thing. I think if people portrayed the arguments and problems with cops in a way that cops (and cop supporters) can keep their pride... life is going to be a lot better.
At the end of the day, Cops have more pride in their work than other government workers (compared to... say... Motor Vehicle Administrations or TSA Airport scanners). When you push on Cops, they push back because of their pride.
But its not necessarily a bad thing. You just gotta keep the pride in mind when you propose police reform. Otherwise, it becomes very difficult to get the individual officers to reform with the law.
