It's an opinion built up over repeated interactions with police. Of course the Yelp effect applies to police but even my positive interactions with police have left me with an impression that public safety and in some respects law enforcement itself is not their primary motivation for being police. In the absence of a comprehensive psychological analysis covering a geographically distributed sample of police with a large sample size, my own experiences are what I fall back on to form my opinions. YMMV.
