I have the soundtrack but not the film. I did see it when it was released on DVD, and I vaguely recall seeing a deleted scene in which Leo DiCaprio's character warns an African American character (also DiCaprio's character's best friend) about the riots. I could be wrong though. However, the character was not only the sole African American character shown in the Draft Riots scene, but he was also lynched. I'm not 100% certain about the existence of the deleted scene, but I have a strong gut instinct saying that I remember actually viewing such a scene.
