An hour before last Tuesday’s accidental shooting at Gardena High School, the campus radiated calm and placidity. I had just finished doing a workshop on homophobia and gender stereotypes with a peer health class headed by the fabulous teacher Debbie Wallace. The campus is a big geographic hybrid. It abuts a train corridor to the west and a phalanx of freeways to the east. The grounds are labyrinthine and rose bushes bloom fiercely in the courtyard. Four parking lots book-end each of the school’s exits.
