Both the sense of entitlement to police action and the compliant behaviour of the police is rather disturbing (as PP say). It puts me in mind of a thought-provoking piece that describes research into individual and collective narcissism:
Research from my PrejudiceLab at Goldsmiths, University of London shows that people who score high on the collective narcissism scale are particularly sensitive to even the smallest offences to their group’s image. As opposed to individuals with narcissistic personality, who maintain inflated views of themselves, collective narcissists exaggerate offences to their group’s image, and respond to them aggressively. Collective narcissists believe that their group’s importance and worth are not sufficiently recognised by others. They feel that their group merits special treatment, and insist that it gets the recognition and respect it deserves. In other words, collective narcissism amounts to a belief in the exaggerated greatness of one’s group, and demands external validation.

It seems that there are several individuals here, some groups, and a validating authority to act as an extension to vent their narcissism on others. Yes, it's a totalitarian nightmare, as summarised by Jane Clare Jones (separate post).
