Frame by frame, a street fight unfolds on the screen before the jury. A woman straddles another woman lying flat on the pavement and punches her again and again.
Standing in the crowd is Shaviya Vinson, wearing a white tank top. The 15-year-old girl is not yet in the fight.
A man pulls the punching woman up.
The fight continues; others rush in. One woman carries a metal shelf and throws it into the crowd.
Angry voices yell for the beating to continue, nearly chanting.
