In the next clip of our exclusive interview with San Fernando graffiti legend HERT USC, he recounts a dramatic close call with the LAPD's feared "Ghost Unit." Hert vividly describes how he and fellow writers, who had gathered at a local writer's bench, took over a city bus, covering it from top to bottom in their trademark graffiti.

Just as the bus was transformed into a moving canvas, the "Ghost Unit" sprung a trap, sealing the doors and cornering the vandals. But through quick thinking and a daring escape, Hert managed to slip away, leaving the others to face the wrath of the LAPD.
