There are lots of people in this world who use the system to make other people's lives miserable. Accuse a LEO of profiling to his CO? You've just created tons of paperwork for that offficer; a letter in his personnel file; an investigation. Whether it's true or not, it becomes a part of that officer's permanent file. Some people just love doing that. It makes them feel powerful.
Of course it matters whether or not it's true. That's the only thing that matters.
