Ugh, you're twisting the words trying to be cute. The point is that assuming you know what a killer looks like or who's harmless based on their appearance is how you end up profiling people. If Primo did something, it doesn't matter what he looked like, and if he didn't, it also doesn't matter. So no, I don't think people are talking about murder because Primo's black, which is what you were trying to suggest. He doesn't "look like a killer", because that's not a thing. No one is reading signs in his face to wonder about that. They're reading a completely absurd situation and trying to draw meaning from it.
