Unless you’ve been hibernating this year (for which you could hardly be blamed), you’ve probably noticed that some people are really angry at cops these days, whereas other people—mostly conservatives and members of law enforcement—are mystified by this and consider the anger almost entirely misplaced. As explained below, I think the anger is largely justified, but for reasons that do not receive as much attention as they should. Perhaps it boils down to the simple fact that it is immoral to enforce morally indefensible laws. Here’s what I mean by that.

Police represent the front line of our criminal justice system. If, as I have argued here before, that system is fundamentally rotten and morally indefensible, then people will naturally direct their ire towards those most responsible for dragging people into it. Human beings come hardwired with various cognitive biases and moral intuitions. Among the most powerful of those is the tendency to condemn those who violate certain taboos, including particularly the rule against harming other people without sufficient justification. If, as I argue below, a strong case can be made that police officers routinely transgress fundamental moral precepts—while disclaiming any responsibility for doing so—then continued loss of confidence and corresponding anger towards them becomes much easier to understand.

Before considering whether people are legitimately angry at police as an institution, we should keep two points in mind. First, people who behave immorally don’t get a free pass simply because they also do good. In other words, just because you invented the polio vaccine doesn’t mean it’s OK to steal candy from children whose lives you saved. Second, people don’t have to be unequivocally right in order to be justifiably angry. Consider studies from last year that reviewed cops’ Facebook pages and found a shocking amount of explicitly racist commentary. While that certainly doesn’t support the proposition that most cops are racists, it raises perfectly valid questions about why the system seems so tolerant of people who express those views and why they’re not hounded out of the vocation by their fellow officers.
