If you want to try to paint a picture of the modal murder in the U.S., it's "Young brown man argues with other young brown man about something silly, things escalate, someone pulls out a cheap pistol and shoots the other guy"
Gang murders, while profitable fodder for mass media, are a clear minority.
And, I should note, "violent gangs" are by definition going to be the gangs committing violence, so that's a circularity in your logic. And I would also wager that there is a very strong correlation between gang membership and skin color, so that's a problem too.
