Five Finger Death Punch - Blue On Black Lyrics Meaning

People aren't going to like this one. And it's not my opinion, just a possible interpretation. Taking from other interpretations, if "blue on black" does have to do with violence between cops and minorities, I think they are saying that type of violence is but a drop in a bucket compared to, say, black on black violence, or crime of another nature. Saying that something is like blue on black, they are saying it's a small percentage of a total larger scale of issues.
