The police targeted Luis and his friends because of their race. Luis and his friends seem to respond in kind, attacking students who are white, even if these students have done nothing wrong. Luis even attacks Asian students, showing how his thirst for violence makes him irrational and pointlessly destructive. In passages like this, Luis reminds readers that he’s not a “good guy”— he’s done some horrible things in his life. It’s also clear that the LAPD have trained Luis and his friends to think in racial supremacist terms: the LAPD attacks non-whites, so Luis and his friends retaliate by attacking non-Latinos.
