If Wesley Snipes was white. he would end up with Yancy Butler?

Read the wikipedia.

Long and short of it, yes.

When the two cops enter the room in which the final fight takes place, not knowing who were the baddies, I think it was made clear one of them shoots at Pete Nessip (and misses him fortunately) because he's black.

and if it was real life they would probably end up doing heroin together
