I don't understand your comment. My point is, because you don't know the officers, inmates, or the broader situation, you shouldn't comment as to whether the officers are right or wrong - because you don't know.

There are possible worlds where the officers are justified or misunderstood and there are possible worlds where the officers hold incorrect beliefs. What evidence lets you know which possible world is more likely?

Being prejudiced against the officers strikes me as similar to the imagined (and possibly real) situation where the officers are prejudiced against the inmates. We, as readers, just don't know.
