You seem to have your story bass-ackwards.
Black girl parks illegally. Black guy gets out to store.
White guy argues with black girl.
Black guy hears about argument and comes out.
Black guy pushes white guy onto pavement.
THEN white guy shoots while on ground. (Yes, WG may have not had to if BG was “retreating”, which he seemed to have finished his point with the pavement.)
I don’t see anything in the NYP article that shows Miss Jacobs is black.
