What is one quote from the book that supports the theme of American Dream

One of the ideals of the American dream is that, in the eyes of the law, you are innocent until proven guilty......except if you are black. Then most likely you are stereotyped the minute you step into court.

O'BRIEN
[…] You're young, you're Black, and you're on trial. What else do they need to know?

STEVE
I thought you're supposed to be innocent until you're proven guilty?
