In this carefully researched ethnographic account, Robert Garot provides rich descriptions and compelling stories to demonstrate that gang identity is a carefully coordinated performance with many nuanced rules of style and presentation, and that gangs, like any other group or institution, must be constantly performed into being. Garot spent four years in and around one inner city alternative school in Southern California, conducting interviews and hanging out with students, teachers, and administrators. He shows that these young people are not simply scary thugs who always have been and always will be violent criminals, but that they constantly modulate ways of talking, walking, dressing, writing graffiti, wearing make-up, and hiding or revealing tattoos as ways to play with markers of identity. They obscure, reveal, and provide contradictory signals on a continuum, moving into, through, and out of gang affiliations as they mature, drop out, or graduate. Who You Claim provides a rare look into young people’s understandings of the meanings and contexts in which the magic of such identity work is made manifest.
