What page number is this quote on "they grew up on the outside of society they weren't looking for a fight they were looking to belong"

It is not in the book, it is the movie tagline. However the supporting evidence for it is on page 4. " We're poorer then the Socs and the middle class. I reckon we're wilder, too. Not like the Socs, who jump greasers and wreck houses and throw beer blasts for kicks, and get editorials in the paper for being a public disgrace one day and an asset to society the next. Greasers are almost like hoods; we steal things and drive old souped-up cars and hold up gas stationsband have a gang fight once in awhile."
