Never underestimate the diversity of the concept of Justice in those who are uneducated, unwise, and dishonest to what is real. If you try to trace this behavior you'll find truly random causes. There are an infinite number of ideas one can substitute for something they don't know or willfully ignore in their own perceived interests. The real problem is when those substitutions are guiding determinations for someone with authority over others.

I'll also add: when I was a teenager I've been in this position countless times, reporting security issues at school, etc. The reactions I received from fully grown adults was nothing short of stochastic. This fascinated me enough to minor in political science and philosophy/ethics. I draw on that for insight, but it doesn't really provide a final answer.
