Mexican gang-banger (Bald Hispanic).
I do see what you said about not understanding. It isn’t clear from the story that anyone but the cops shot their firearms in either confrontation. All we have on the Mexican at this point is that he backed into the officer at the initial traffic stop.
After that ‘shots were fired’ but with no information on who fired the shots, it may have been an all-cop shooting, with the police catching some friendly fire.
See my post with the broadcastify link. It is ongoing
