Is there a possibility for peace? Chapter 8?

In Chapter Eight, we see a possibility for peace, as the gangs join together to see justice after the killing of Miguel Robles. The peace, however, is short lived, and the gangs begin fighting again. It is important to note, that this chapter leaves us with the feeling that peace can be achieved based upon Luis' individual actions and his belief in what Chente taught him... the importance of sticking together as a community.... as Chicanos.
