To be a young black man in America is to live in conflict. A black president is proof that anything is possible. Trayvon Martin, Michael Brown and others remind us that that promise can be taken in an instant.

He explores these topics and more in his book “Invisible Man, Got the Whole World Watching: A Young Black Man’s Education” (Nation Books).
