Luis describes the process of gentrification by which impoverished, largely minority-populated areas of the city are taken over by affluent, mostly white families. Notice, also, that Luis doesn’t describe gang violence in purely negative terms. Instead, he characterizes it as a form of rebellion. While Luis is critical of gang violence, he’s also realistic enough to see it for what it is: a rational response to racism, poverty, police brutality, and cultural genocide in Los Angeles.
