Through this conversation, readers learn how rampant corruption is in the Coconut Cove police department. Everyone in this meeting seems to know, on some level, that Dana isn’t the real vandal. And yet, they’re so concerned with looking competent to the Mother Paula’s corporation that they’re all willing to try to charge and imprison Dana, who’s essentially innocent (even if he’s guilty of various other crimes). And threatening the sergeant and Delinko with parking duty is a threat to end their careers if they don’t cooperate, which discourages them from doing the morally right thing (searching for the real vandal).
