Continuity mistake: While Fox is struggling with the cop at the subway, in one second they are on the edge but in the next one now they are like one foot away.
Continuity mistake: It is way obvious during the first Gramercy Riffs scene (over who killed Cyrus) that the lights reflecting in the Riff leader's sunglasses are location camera lights, as the warehouse has only track lighting.
Continuity mistake: Snow's afro changes length throughout the movie. In the beginning it's medium length, when they fight the Punks later in the movie his afro is longer.
Continuity mistake: Rembrandt's hair constantly changes throughout the movie from fluffy to a more cut style.
Continuity mistake: The gang members' shadows during the Coney Island scene change from shot to shot. In some shots they are to the side of the actors and in others behind them.
Answer: The Riffs were informed of the Warriors' innocence of wrongdoing by a member of another gang who had no reason to lie on behalf of the Warriors or to frame Luther (the actual culprit).
