Thread: Respectfully reporting a crime

So I was just reading "The Production of Crime Rates" by Donald Black, and I was particularly intrigued by the statistics the author shares about the deference of complainants. In a passage, Black states that more respectful complainants/citizens were more likely to have their wishes for an official report fulfilled.

Spoiler for Passage from the book:

Evidence accumulates from studies of police sanctioning that the fate of suspects sometimes hangs upon the degree of deference or respect they extend to policemen in field encounters (Westley, 1953; Piliavin and Briar, 1964; Black, 1968; Black and Reiss, 1970). As a rule, the police are especially likely to sanction suspects who fail to defer to police authority whether legal grounds exist or not. Situational etiquette can weigh heavily on broader processes of social life (see Goffman, 1956 and 1963). This section offers findings showing that the complainant's deference toward the police conditions the official recognition of crime complaints.

So I am wondering: Is this fair? Do you think policemen have a right to not report a crime because the complainant was rude? Does this make the complainant less victimized? At first this bothered me, until I remember that policemen simply cannot investigate every crime, and must be discretionary about which they do investigate, so I think now there is an argument for either side. What does everyone think?
